Re: How to format datetime stamp in JS like it is doing by the date template tag?

[the.one.abo...@gmail.com]

Hello, thanks for your reply! 

The DATETIME_FORMAT setting of Django uses format strings that are 
incompatible with JS. E.g the default DATETIME_FORMAT value in Django is 'N 
j, Y'. 

You can check the allowed format strings in Django documentation 

.

Re: How to format datetime stamp in JS like it is doing by the date template tag?

[Matthias Yeni]

To format the timestamp in JavaScript according to the format defined by
Django, you can use Django settings to determine the format and adapt it in
JavaScript. Here's how you can do it:



Retrieve the date and time format defined by Django in your JavaScript file
using a Django template rendering method.







  // Get the date and time format defined by Django

  var dateTimeFormat = "{{ DATETIME_FORMAT }}";





Use the Moment.js JavaScript library to format the timestamp based on the
format retrieved.



https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js
">



  // Convert current date and time using Moment.js

  var currentDateTime = moment();



  // Format date and time using format retrieved from Django

  var formattedDateTime = currentDateTime.format(dateTimeFormat);



  // Use the formattedDateTime variable wherever you want to display the
timestamp in your page  console.log("Horodatage formaté :",
formattedDateTime);





With this approach, your JavaScript code will automatically adapt to the
date and time format set by Django based on the LANGUAGE_CODE, USE_I18N,
and USE_L10N parameters, without needing to hardcode the formatting of the
datetime string into your JavaScript code.

How to format datetime stamp in JS like it is done by the date template tag?

[the.one.abo...@gmail.com]

Hello everyone, 

I am customizing Django admin by adding a datetime stamp to the page using 
JavaScript. I want to format the datetime stamp according to the format set 
by Django. 

It is possible to get the DATETIME_FORMAT using the get_format() method in 
JS which is "'j M Y, P'". But, this format is not supported by the 
Date().strftime method. 

I don't want to hard-code the formatting of the datetime string. I want the 
code to adapt according to the Django settings for LANGUAGE_CODE, USE_I18N, 
and USE_L10N settings.

TIA!

Gagan Deep

You can set custom template folder in you project directory

Change template path from setting
You can look into documentation.

Re: NoReverseMatch if "url" template tag not used with app_name

[Franz Ulenaers]

It seems you have specified an app_name in your post/urls.py :

*app_name='post'*


Have you different name='home' in your apps then you have to use the 
app_name to make it unique !!

I understand what you are trying to explain.

I have used name=“home” for home view. I’m using urls.py for my app(main 
URLs.py to route me to my apps urls.py, app urls.py contains path(‘’, 
HomeView.as_view(), name=‘home’)

But when I try to reference this url in templates ({% url ‘home’%})I get 
NoReverseMatch error.

However if I use {% url ‘post:home’ %} it works

post is my app name

[Exactly musty]

You are using django url, so it should be the same name you gave your url in 
your URLs.py e.g path('',homeview.as_views, name='home-page') 

So if I want to call this url in my template I will use the django url which is 
{% url 'home-page' %}.

You will have to check your url and see if what you named it matched what you 
wrote in your django template

NoReverseMatch if "url" template tag not used with app_name

I just want to confirm if there has been a change in Django3.x

In Django2.x i could write something like
**
where 'home' is a url pattern in one of my apps(not the main url file)

But I get NoReverseMatch when I use the same in Django3
I have to use this convention
**

Which one is correct, for Django3.x?

 The reason I want to do this is:

 From a list of all names:

 The name comes from a model that has a foreign key to another model
 that has actions performed by that name by date and I want to output the
 action taken on that date so something like:

 from django import template
 from django.conf import settings
 from django.utils.html import escape
 from user.models import person
 from action.models import data

 def (get_action):
 action = Data.objects.get.filter(person=name).filter(date=date)
 return action

 but how do I pass the variables in the 1st place please?

RE: template tag help please?

[Mike Jones]

Andreas,  

Thank you for your help and patience I have got the damned thing working!!  

It helped that I remembered that one of the filter arguments was actually a 
foreign key in the model and had to be an integer id not a string,  that was 
being obfuscated by being a templatetag call.

 

Thank you

Yes - but you still are doing it strange - you shouldn't use kwargs if you are 
sending the parameters and have the parameters in the function - use the 
parameters.

 

In other words: 

avn = kwargs['avn']

avd = kwargs['avd']

name = kwargs['name']

 

That is unnecessary

Andréas

Wait a secound, you are doing some very strange things

 

I didn't see this before.

 

You have defined the following:

@register.simple_tag
def do_cost( name, avn, avd, *args, **kwargs ):
avn = kwargs['avn']
avd = kwargs['avd']
name = kwargs['name']
return name

 

The method has 3 parameters that you are sending to it - name, avn and avd. 
They correspond to the values sent to the method in order. So you don't need to 
use the kwargs dictionary - it's unnecessary...

You could just write:

@register.simple_tag
def do_cost( name, avn, avd, *args, **kwargs ):
return name




Beacause you have sent the name to the method?

 

Regards,

 

Andréas

Thank you Andreas Kuhne, progress

 

So this {% load get_cost %}{% do_cost b.name avn avd %} was working quite 
happily but for some reason is now complaining 

 


Exception Type:

TemplateSyntaxError


 Exception Value:

Caught KeyError while rendering: 'avn'

 

Exception Location claims to beget_cost.py in do_cost, line 10  which is 
avn = kwargs['avn']

 

but the exception is in the template line {% load get_cost %}{% do_cost b.name 
avn avd %}

Probably you don't need template tag at all, try {{ b.name }}
if you just need to get name value from b

RE: template tag help please?

[Mike Jones]

Ah I was just doing that to prove it was working

 

This is the actual tag

 

from django import template

from django.conf import settings

from django.utils.html import escape

from band.models import Data

 

register = template.Library()

 

@register.simple_tag

def do_cost( name, avn, avd, *args, **kwargs ):

avn = kwargs['avn']

avd = kwargs['avd']

name = kwargs['name']

val_set = Data.objects.filter(prop = name).filter(date_period=avd)

avn = 7  #this line is just for testing

if avn >= 7:

for x in val_set:

val = x.full

else:

for x in val_set:

val = x.short

return val

Wait a secound, you are doing some very strange things

 

I didn't see this before.

 

You have defined the following:

@register.simple_tag
def do_cost( name, avn, avd, *args, **kwargs ):
avn = kwargs['avn']
avd = kwargs['avd']
name = kwargs['name']
return name

 

The method has 3 parameters that you are sending to it - name, avn and avd. 
They correspond to the values sent to the method in order. So you don't need to 
use the kwargs dictionary - it's unnecessary...

You could just write:

@register.simple_tag
def do_cost( name, avn, avd, *args, **kwargs ):
return name




Beacause you have sent the name to the method?

Hi,

You don't need the {{}} when sending a variable to the template tag - try
removing them.

Re: template tag help please?

I am so rusty I’m having trouble writing a simple_tag

 

In the template

 

{% for b in list %}

{% load get_cost %}{% do_cost {{ b.name }} avn avd %}

 

Also tried (per docs) {% do_cost name={{ b.name }} avn=avn avd=avd %}

I definitely have values in the template passed from the view for avn and 
avd and of course b.name 

 

Tag

from django import template

from django.conf import settings

from django.utils.html import escape

from band.models import Data

 

register = template.Library()

 

@register.simple_tag

def do_cost( name, avn, avd, *args, **kwargs ):

avn = kwargs['avn']

avd = kwargs['avd']

name = kwargs['name']

 

val = Data.objects.filter(property=name).filter(date_period=date)

return val

 

I just keep getting do_cost takes 3 arguments

*** I know I want it to take 3 arguments***

Is it telling me that I can’t use {{ b.name }} as an arg?

Re: template tag help please?

Yes

 

For example, in the filter {{ var|foo:"bar" }}, the filter foo would be 
passed the variable var and the argument "bar".

 

I want to pass 2 (maybe 3) variables and correct me if I am wrong but 

Custom filters are just Python functions that take one or two arguments:

 

So could do  {{ var|foo:”bar, bar2” }}

or {{ var|foo:”bar” “bar2” }}   and pass 2 arguments?   The doc doesn’t 
specify 

 

I assume if 2 args

def cut(value, arg1, arg2):

 

?

template tag help please?

[MikeKJ]

I want to pass 2 variables to a templatetag from within a template, a name 
and a date (eg, John 29/09/2018) to output the result of the templatetag 
def.

The reason I want to do this is:

>From a list of all names:

The name comes from a model that has a foreign key to another model that 
has actions performed by that name by date and I want to output the action 
taken on that date so something like:

from django import template
from django.conf import settings
from django.utils.html import escape
from user.models import person
from action.models import data

def (get_action):
action = Data.objects.get.filter(person=name).filter(date=date)
return action

but how do I pass the variables in the 1st place please?

NoReverseMatch when trying to use get_absolute_url with custom template tag

[Will Holmes]

I am making a calendar app which has a custom template tag that takes the 
python HTML template function and overlays objects from the Events model on 
the correct days. I am trying to get the displayed objects to have a link 
directly to an object detail/edit view and am trying to use 
get_absolute_url and to reverse render this view. This is necessary as the 
custom template tag doesn't load correctly if I try to hardcode {% url %} 
template 
tags into it for each event via a for loop. I have spent some hours looking 
through stack overflow questions with no luck and have even changed my 
reverse to the object ID rather than the title of the event. I am hoping 
this is just a small thing that I have overlooked but no sure.


view:

def home(request, month=None, year=None):
if month == None:
_date = datetime.now()
else:
_date = date(int(year), int(month), 1)
title = "%s, %s" % (_date.strftime("%B"), _date.strftime("%Y"))

return render(request, 'calendar.html', calendar(_date, title))


url:

app_name = 'cal'
urlpatterns = [
url(r'^$', views.home, name='home'),
url(r'^newevent/$', views.newEvent, name='newevent'),
url(r'^(?P\d+)$/', views.viewEvent, name='viewevent'),
url(r'^(?P\d+)/(?P\d+)$', views.home, name='another-month')]


HTML:


  {% load calendarify %}
  {% calendarify year month event_list %}



Template tag relevant function:

def formatday(self, day, weekday):
if day != 0:
cssid = self.cssclasses[weekday]
cssclass = "daybox"
if date.today() == date(self.year, self.month, day):
cssid += ' today'
if day in self.events:
cssid += ' filled'
body = ['']
for event in self.events[day]:
body.append('')
body.append('' % event.get_absolute_url())
body.append(esc(event.title))
body.append('')
body.append('')
return self.day_cell(
cssclass, cssid, '%d %s' % (
day, ''.join(body)))
return self.day_cell(
cssclass, cssid, '%d' 
% (day))
return self.day_cell('nodaybox', 'noday', ' ')


Model:

class Events(models.Model):
...

def get_absolute_url(self):
return reverse('cal:viewEvent', args=[str(self.id)], current_app='cal')

Re: "trans" template tag using wrong language

[Joan Perals]

Hi Antonis,

I think I figured this out. I have English as fallback language (LANGUAGE_CODE 
= 'en') in the settings, but my source language is German, and this 
mismatch seems to have been the source of all the trouble. Providing German 
translations (even if the original strings are already in German) seems to 
solve the issue.

Thanks for your help in any case,

Joan

Re: "trans" template tag using wrong language

[Antonis Christofides]

It's very unlikely that such a basic behaviour won't work, so probably you are
doing something wrong (and so's the stack overflow poster). I made several
related changes in an app yesterday and I had absolutely no problem with {%
trans %} (but I'm using 1.8).

Do you have USE_I18N = True?

If in the template you use

  {% get_current_language as current_language %}
  {{ current_language }}

does it show the correct language?

"trans" template tag using wrong language

[Joan Perals]

I have a site using Django 1.10 with German and English as available 
languages, where German is the source language. Dynamic content is 
translated with django-modeltranslation and for static strings I am using 
Django's built-in `trans` template tag.

I want Django to return the page in the visitor's preferred language. I 
have read how Django discovers language preference 
<https://docs.djangoproject.com/en/dev/topics/i18n/translation/#how-django-discovers-language-preference>
 
several times, and I think I have everything right. As I change my language 
settings in my browser, the value of the `LANGUAGE_CODE` variable when 
displayed in a template always changes accordingly, and also the dynamic 
content is always returned in the expected language by 
django-modeltranslation. The locale middleware is of course in place, and 
so are the *.po and *.mo files as well. The browser request headers also 
look fine. But *it's only the `trans` template tag that is not picking my 
browser's language preference*. Instead, *it seems to directly resort to 
the initial value of the `LANGUAGE_CODE` variable as it is originally set 
in the settings file, without going through the algorithm described in the 
link above*.

Is this known? Certainly not what I expected, and it took me a lot of 
effort to narrow down the issue.

Thanks in advance for your help,

Joan

Re: Custom Template Tag

['Abraham Varricatt' via Django users]

The idea of doing a POST request during template rendering seems weird. As 
others have mentioned - that's not the place for it. 

But perhaps you issue could be a matter of performing your POST operation 
on the client side, instead of the django server? In that case, it might be 
worth investigating if you could code in some JS inside your template so 
that when the client's browser loads it, the POST operation is called and 
changes are made appropriately on the site. 

Yours,
Abraham V.

Re: Custom Template Tag

[Al Johri]

I'm experimenting with creating templates out of subtemplates. These 
subtemplates can be either (a) simple text or (b) a hash representing a 
sentence (i.e. {subject: "Dog", verb: "eat", object: "my {{var}}", tense: 
"past"}). I would like to run the hashes through a realization engine which 
would render as "Dog ate my homework" given a context dictionary of {var: 
"homework"}. The realization engine is accessed via a REST API.

Does that make sense?

Re: Custom Template Tag

[Constantine Covtushenko]

Hi All,
There is no valuable reason to do it in the template. And no matter how to
ate using it, cause template should only present view model(s).

But if you tell us your intention may be we can suggest a better place for
such request?

Re: Custom Template Tag

[ludovic coues]

I wouldn't do it this way.
Personally, I would make the POST request in the view function, put
the return value in the context. The template isn't a good place to
have logic. It should only take data and format them.

Custom Template Tag

[Al Johri]

Hi Django Users,

I want to make a custom template tag where the tag's renderer needs to make 
a POST request.

https://docs.djangoproject.com/en/1.10/howto/custom-template-tags/#writing-the-renderer
https://docs.djangoproject.com/en/1.10/howto/custom-template-tags/#thread-safety-considerations

Is it possible to render the nodes of a template in multiple threads? I 
would ideally like those POST requests to happen at the same time.

Does anyone know of some similar project?

Thanks,

Al

Fwd: Built In Template Tag Request

[Paul Kenjora]

Hello,

  I sometimes have to pass more complex content into an include or another
tag as a variable.  The {% with %} tag and filters aren't enough to for
example render an HTML button and pass it into another include.

  I'd like to request a {% with_html variable %} tag in the built in tag
set.  Like the one below

@register.tag
> def with_html(parser, token):
>   nodelist = parser.parse(('endwith_html',))
>   parser.delete_first_token()
>   return WithHTML(nodelist, token.contents.split()[1])
>
> class WithHTML(template.Node):
>   def __init__(self, nodelist, variable):
> self.nodelist = nodelist
> self.variable = variable
>   def render(self, context):
> context[self.variable] = self.nodelist.render(context)
> return ''


A use case would be for example...

{% with_html extra %}
>   {% if row.0.ingredient_set.count %}{{ row.0.ingredient_set.count }}
> Ingredients{% endif %}
>   {% if row.0.step_set.count %}{{ row.0.step_set.count }} Steps{%
> endif %}
> {% endwith_html %}
> {% with item_title=row.0.title item_description=row.0.description
> item_image=row.0.image item_extra=extra item_link=row.0.link
> item_button=newsletter.recipe_button %}
>   {% include "newsletter/email_full.html" %}
> {% endwith %}


This type of tag would help keep the code more DRY in my opinion since the
rendering logic for the complex content doesn't need extra files and I can
now make includes more generic.  It would be a great compliment to the
already existing with tag.

Re: [django1.9] Url template tag, dotted path and decorator

[knbk]

In order to reverse a view by its dotted path, Django needs to know the 
actual path of the function. It uses the magic view.__module__ and 
view.__name__ attributes to determine the name. If your decorator doesn't 
copy these attributes from the inner function to the decorated function, 
Django doesn't know the path to the original function, and you can't 
reverse by dotted path.

As mentioned by Camilo, you can use functools.wraps() to fix this issue.

[django1.9] Url template tag, dotted path and decorator

[François Magimel]

Hi!

I'm facing an issue reversing a dotted path with django 1.9.4. Here are more 
details.

I pass a dotted path to the django template tag "url":
"{% url 'my.app.view.func' arg %}"
And the function "my.app.view.func" has a decorator which is using "arg". My 
problem is : when displaying my template, I get a NoReverseMatch error.
But I don't have any error:
  - when I use the name of the url (defined in my urls.py file) or
  - when I use the dotted path and remove my (simple) decorator.

I know that passing a dotted path to url is deprecated since django 1.8 [0][1], 
but not removed yet. So, I think there is something wrong with dotted path and 
decorators, but I can't find what…

PS: my decorator only redirects to another view…

Thanks,
François

STATIC_URL with thumbnail_url Template Tag

[Stephanie Socias]

Hello,

I'm trying to use an image from my 'static' folder in one of my templates. 
I need to pass the image into the thumbnail_url filter but I can't get it 
to work. The image is not found. How do I specify the correct image path? 
(I posted this same question on stackoverflow 
<http://stackoverflow.com/questions/31125560/static-url-with-thumbnail-url-template-tag>
 
yesterday.) Thank you!

I've tried this:

{% load thumbnail %}


{% with path="{{STATIC_URL}}/images/green-icon.png" %}

{% endwith %}


and also:

{% load thumbnail %}{% load staticfiles %}

Just to follow up, I found the problem. The search url pattern had an 
optional trailing '/', so it was not creating the url correctly. Once I 
removed the optional from the regex, it worked.

Problem with url template tag and namespaces

[donarb]

I'm having a problem with a generated url using the url template tag, 
currently using Django 1.6.5.

The appname is 'dashboard', here is the main urls.py:

urlpatterns = patterns("",
(r'^dashboard/', include('dashboard.urls', namespace='dashboard')),
)



Here is the dashboard urls.py:

# dashboard/urls.py
urlpatterns = patterns("",
(r'^players/', include('players.urls', namespace='players')),
)


Here is the players urls.py:

# dashboard/players/urls.py
urlpatterns = patterns("",
url(r'^search/?', views.PlayerSearchView.as_view(), name='search'),
)



When I code this in the template:

{% url "dashboard:players:search" %}



I get this url:

/dashboard/playerssearch


Any idea why there is no path separator between 'players' and 'search'?

Like the error says, you are telling it to split the result of 
`token.split_contents()` into three variables, but you are only passing it 
two elements: "rowcolour" and "flow.created". Where is `fmt` supposed to be 
coming from?

However, even when you fix that, this still won't work, as at that point 
`dt` will just be the string "row.created". You need to have a whole 
template Node in order to resolve variables like that. Why are you not 
using the `simple_tag` decorator, which is a shortcut for that whole 
process?

@register.simple_tag
def rowcolour(dt):
diff = datetime.now() - dt 
...etc...

Problem with a token in my custom template tag

[Daniel Grace]

Hi,
I'm encountering the following problem with a token in my custom template 
tag:
Request Method: GET
Request URL: http://127.0.0.1:8000/flows/
Django Version: 1.7
Exception Type: ValueError
Exception Value: 
need more than 2 values to unpack
Exception Location: C:\landy\cresta\flow\templatetags\flow_extras.py in 
rowcolour, line 7

Here is the template file:
from django import template
from datetime import datetime, timedelta
register = template.Library()

@register.tag
def rowcolour(parser, token):
nm, dt, fmt = token.split_contents() # this is line 7
diff = datetime.now() - dt 
if diff.days > 14:
return "pinkrow"
else:
return "greyrow"

... here is the line in the html file:


... and "created" is defined as follows in the model:
created = models.DateTimeField(db_index=True, auto_now_add=True)

I'm trying to extract the datetime from the token.  Any ideas?

Thanks.

Combining use of template tag + filter in same expression

[Darren Spruell]

I have a template in which I'm trying to achieve the use of the
'firstof' tag to display whichever of two variables is present, and
the resulting variable filtered through 'truncatewords'. Is there a
way this can be accomplished?

Have tried the following:

{% first of result.meta.summary|truncatewords:12
result.description|truncatewords:12 %}

It doesn't work as I thought it might, instead rendering 'None' in the template.

This construct seems to work as expected if only the last variable is
applied the filter:

{% firstof result.meta.summary result.description|truncatewords:2 %}

Can this be made to work? Or is the combination of firstof and a
filter on more than the last variable unsupported?

Differing types? "1" != 1

Log the repr of both values and see.

testing equality in template tag

[Lee Hinde]

with view code like so:

import calendar
months_choices = []
for i in range(1,13):
months_choices.append((i, calendar.month_name[i]))
context['months'] = months_choices


and

context['default_month'] = today.month

I have this snippet in a template (my first use of lists like this):


{% for month in months %}

{{ month.1 }}
{% endfor %}



The issue is the  {% if default_month == month.0 %} always returns false...
The rest of the select is properly built - I get a number for the value and
the month name as the label.

Re: Template tag render method doesn't get called

[stevedegrace]

This is a real problem. I have had the same issue, and I have seen several 
other people besides yourself bring this up without getting satisfactory 
answers.

I was having the same problem where __init__ was being called but not 
render, where the purpose of the tag is to insert several variables into 
the context and all it does is return an empty string. I don't know if this 
will work in your context, but it did in mine.

I was using the tag in a child template that extends by base template. I 
put the tag right after the load statement, but, *not within a {% block %}.*

When I put the tag within a block that is rendered, the render method got 
called and problem solved.

Re: Empty context within template tag render() method after using django.test.client.Client.login() method

Empty context within template tag render() method after using django.test.client.Client.login() method

[jondbaker]

Within my integration tests, it appears that after using the login() method 
of django.test.client.Client the context dict consists only of: 

[{'False': False, 'None': None, 'True': True}, {}, {}].

If I remove the use of login(), then the request dict consists of:

[{'False': False, 'None': None, 'True': True}, {'object': , 'user': , u'view': 
}, {u'csrf_token': 
}, {'perms': 
, 
'user': }, 
{}, {u'MEDIA_URL': '/media/'}, {'messages': 
}, {u'request': ,

I noticed the problem when a template tag was trying to access 
context["request"].path and a KeyError was raised after using login. Both 
outputs above are the result of printing the context var from within the 
render() method of a template tag. Any help would be greatly appreciated, 
as I'm a bit stumped.

Jonathan

Re: How template tag can receive values JS

[Bill Freeman]

If this is only to be done when loading a new page, then you could add the
JS var value to the request as a query parameter.  Then the view would have
to pass the value to the template for the new page.

How template tag can receive values JS

[Christian Erhardt]

No, what you are trying is not possible. The template tags are rendered on the 
server. They never appear on the client machine. Javascript is running on the 
client machine. They both will never see each other.

You will always have to do a roundtrip to interact between Javascript and 
django templates: send a request from Javascript to the server, server renders 
the page and returns it.

You could pass something from js using ajax back to python, which then
passes it to a template.

How template tag can receive values JS

[Mário Idival]

Good morning everyone,
I wonder how I can do (and if it is possible), pass a value of javascript
variable to a template tag Django.

eg
how it works:
{{Document.id | split_filter}} -> split_filter is just a random method,
receives an ID

as would
{{"Value Var JS" | split_filter}} -> pass the id that comes from a JS
variable to the template tag.

Thanks.

django dynamic template tag

[Fadi Samara]

 

I try to build a plugins based application, I have created tags and

I have a table stores each page plugins, and need to render any stored

Now for the template i use this:

{% block slider_region %}{% for pagecontent in pagecontents %}
{% pagecontent.plugin %}{% endfor %}{% endblock %}

But this returns:

Invalid block tag: 'pagecontent.plugin', expected 'empty' or 'endfor'

Access request object in a custom template tag

[Ponytech]

Hello,

I am currently writing a custom template tag and I need to access the 
request object within the tag code.
When using tag helpers (*simple_tag*, *inclusion_tag *and *assignment_tag*) 
you can register them with an additional takes_context=True parameter that 
makes the request object available.
But this does not work with the low level *tag* decorator:

@register.tag(takes_context=True)def mytag(parser, token):
   ...

raises the exception:  *tag() got an unexpected keyword argument 
'takes_context'*
*
*
2 questions :

- is there a reason why the tag decorator does accept the takes_context 
argument ?
- how can I access the template context with this decorator (and thus the 
request object) ?


Thanks a lot.

Re: {% url %} template tag not resolving app url in template

[Sithembewena Lloyd Dube]

Issue resolved.

The problem was a similar usage of a url template tag without a namespace -
in the same template. All I had to do was check the correct line number in
the template.

Thanks to all. Time for a walk outside.

Re: {% url %} template tag not resolving app url in template

Hi all,

I have the correct url, but the dev server seems to be caching my old
template, even though I updated it to include namespacing. I have restarted
the server and cleared my browser cache.

The latter. I did not call reverse explicitly (not yet). I have implemented

Are you saying that this url was the result of calling reverse() (or {% url %})?

In your template you have

  {% url 'contact_us' %}

But in your urls.py you have given all urls in that app a namespace.
Therefore, you must use the namespace if you wish to reverse it - the
url tag simply calls reverse(). Hence:

  {% url 'contact_us:contact_us %}

Cheers

Re: {% url %} template tag not resolving app url in template

[Sithembewena Lloyd Dube]

Hi Tom,

I see what you meant. In the documentation (tutorial) namespacing is used
in the form example. Even with that in place, I am having trouble.

I did notice that I am not getting a 404 error instead, because the url
being built is dumplicated. Please see the trace below (errant line ibeing
#8):

 Using the URLconf defined in mysite.urls, Django tried these URL patterns,
in this order:

   1. ^$ [name='plant_refurbishment']
   2. ^about_us/$ [name='about_us']
   3. ^instrumentation_and_control/$ [name='instrumentation_and_control']
   4. ^machining/$ [name='machining']
   5. ^industrial_solutions/$ [name='industrial_solutions']
   6. ^trailer_refurbishment/$ [name='trailer_refurbishment']
   7. ^trailer_spares/$ [name='trailer_spares']
   8. ^contact_us/ ^$ [name='contact_us']
   9. ^admin/

The current URL, contact_us/contact_us/, didn't match any of these.

Thanks, Tom.

I am not sure how you mean? In the contact_us app, I am not explicitly
calling reverse. I only have the following:

from django.shortcuts import render, reverse

def contact_us(request):
return render(request, 'contact_us/contact_us.html')

You've omitted the namespace when reversing the url. Use
'contact_us:contact_us'.

[Andrey Kostakov]

I am not sure, but you can try following code in your contact_us app's urls.py:
urlpatterns = patterns('contact_us.views',
url(r'^$', views.contact_us, name='contact_us'),

Re: {% url %} template tag not resolving app url in template

[Sithembewena Lloyd Dube]

Hi Andrey,

Thanks for the suggestion. I tried that with no success. According to the
current documentation, that would be an issue with versions older than 1.5?
(where one would use url from future).

For some reason, i suspect that the url tag cannot resolve a url for a view
in a "plugged-in" app? (base url + app-view url?).

{% url %} template tag not resolving app url in template

[Sithembewena Lloyd Dube]

Hi everyone,

I have a project based on the latest Django version (1.5.1.) where I
created a contact_us application. The project has a urls.py file with some
url patterns. The contact_us app implements its own urls.py file
(decoupling). In the project's urls.py file (just above the admin site's
url pattern), i have the following url pattern:

url(r'^contact_us/', include('contact_us.urls', namespace="contact_us")),

and in the contact_us app's urls.py file, I have the following url pattern:

urlpatterns = patterns('',
url(r'^$', views.contact_us, name='contact_us'),
)

In a template residing in the contact_us app's own templates folder, I use
the url template tag as follows:

Contact Us

resulting in the following exception:

*NoReverseMatch at /contact_us/*

Reverse for 'contact_us' with arguments '()' and keyword arguments '{}' not
found.

Any ideas what I could be missing? I namespaced the contact_us urls include
in the main urls'py file and there is a simple contact_us view in the
contact_us app which renders an existing template.

Thanks.

Re: 'url' template tag throws and error after upgrading to 1.4

[Bastian]

I am trying now in a brand new environment, I have set up a new os, a new 
virtualenv with all the dependencies upgraded to latest versions, and I 
installed the project from the repository. It loads with debug = False, quite 
strange. I need it to work with debug = True and I want to understand what is 
wrong. Thanks for the help.

Re: 'url' template tag throws and error after upgrading to 1.4

[Bastian]

I'm not sure what you mean with 'connect to views'. In this case Django is 
complaining about the URL tags, the first one that gives an error tries to load 
django.views.i18n.javascript_catalog. When I manage.py shell I can do from 
django.views import * without problem. 
I really have no clue, maybe it is related to the static files in a way.

Can you run manage.py shell and connect to 'views?'
