Re: Session backend for production

[Parth Joshi]

Cache implementation will be definitely use faster if you are using MVT. If 
using REST (DRF) then token Auth definitely helps.

Re: Customer specific translations

[Mike Dewhirst]

On 25/11/2019 11:11 pm, Jani Tiainen wrote:
I've use-case where my django app is delivered to multiple customers 
in multiple languages.


Due the nature of application end users do use for certain terms their 
own wording, which differ significantly from others.


For example:

"Delivery route". Some may call it "driving route". Some "route" and 
some just "delivery route".


I love this. It means the customers are involved and taking ownership. I 
think it is worthwhile making it a feature of all/most apps. It could 
even be built into Django one day.


It probably means building a special app to let customers enter their 
own terms for certain fields. The app would need to store such terms in 
the database or ini files. Not sure how you might do it but I'd probably 
look at overriding verbose_name. Might bypass the usual translations 
because the customer probably supplies the correct language as well.


def get_verbose_name(obj, field=None):

    if field is None:

    return obj.__class__()._meta.verbose_name

    try:

    return obj.__class__()._meta.get_field("{0}".format(field)).verbose_name

    except FieldDoesNotExist:

    return None



It needs to include drop-down lists too.

def choose(choices, choice):

    # this demands that choices is exactly as Django specifies

    for pair in choices:

    if pair[0] == choice:

    return pair[1]

    for option in choices:

    for pair in option[1]:

    if pair[0] == choice:

    return pair[1]



Please keep us posted with your solution. It is a brilliant use-case.

Cheers

Mike



Any ideas how to handle this?

Re: Trying to update a record using UpdateView Error: Circuitinfotable matching query does not exist

[Gil Obradors]

Hi!
Matching query doesn't exists says that this entry with this id not exists
in db
Are you sure that this object exists? STTK-100G-18040-01-WRBB

Can you open a shell and:

from xxx.models import Circuitinfotable
obj = Circuitinfotable.objects.all()
print(len(obj))
obj = Obj.get(circuitid='STTK-100G-18040-01-WRBB')
print(obj)


Are you following me?
Or confirm that exists via admin?

Re: How to migrate Django site from MySQL database to Postgres?

[carlos]

1. Install your application on the server first, if you have media files,
then copy them from your localhost to the server
2. Do the dumpdata from your local in .json, then copy that json to your
server
3. Once on the server just load that json with the loaddata command.

 Hi Carlos,

 If you get to see my email, could you review my plan and let me know
 whether my plan works for migration.

 1. I have setup new Ubuntu 18.04 server in Digital Ocean droplet
 2. Installed Postgress, Django with default settings and empty site,
 which means I did not bring/copy over the my Django project files yet
 3. My next step is to copy over all the Django project files which are
 located in my developer's localhost
 4. Once the files are copied to project folder in this new server I
 will have to run following commands, but I will not run these because old
 and new sites have same database software.
 4.1.(virtual env) ~/myprojectdir/manage.py makemigrations
 4.2. (virtual env) ~/myprojectdir/manage.py migrate
 4.3. (virtual env) ~/myprojectdir/manage.py collectstatic

 5. So I want to start with your steps pointed in your blog
 
 since I have to start with an empty Postgres database. I'm not sure whether
 this will work or not.
 6. Hopefully if all the commands are successful, I will run the above
 commands.

 Please let me know if my plan generally would work? I know you don't
 have complete picture, but I'm wondering if you have any thoughts about my
 use case?

 Thanks,
 ~Ram

I have a built a database application that users can search and view 
records from.  I am trying to incorporate an update feature to allow users 
to edit information the app is called editLit.  When I try to pass a 
parameter into the editLit app via urls into views.py I get the following 
error:

And finally my template for the editLit class is:

Any ideas about what I'm doing wrong are welcome I am still new to Django.

Session backend for production

[Lorenzo Peña]

Hello, fellow djangonauts!

Is there any particular reason why should I pick memcached backed sessions 
in production over db, or viceversa? Most documentation seems to slightly 
suggest that memcached should perform faster than database. Any other 
criteria I should be aware of? I am using single database for multi-tenant 
application, so I am expecting over-average db traffic.

Thanks in advance!
Lorenzo

Django on an existing PostgreSQL Database?

[Ulrich Goebel]

Hi,

I have an existing PostgreSQL Database with about 20 tables, using 
collating sequences, foreign keys, triggers, and even additional indexes. 
For that database I want to write a WEB-frontend to insert, update and 
delete data in the database. I don't want to define the data model in 
python or django, but want to make django/python work on the existing 
database.

Is that possible? Where to find som helpful hints how to do that?

Best regards
Ulrich

Hello Integr,

I did not understand your suggestion? How do I clear cache in Python
virtual environment? and what is other method you suggest based on the

Re: How to migrate Django site from MySQL database to Postgres?

[Ram]

Hi Carlos,

I see there is a typo in my previous steps which could have mislead you.
Basically old and new sites are different databases. Old site is running
remotely in local host on our Developer's machine with MySQL dB. Now I've
setup new hosting server with Postgres database (empty site so far) in a
Digital Ocean's droplet ( Ubuntu 18.04 OS).  So what I'm planning now is I
will not run these commands in new server's virtual environment

4.1.(virtual env) ~/myprojectdir/manage.py makemigrations
4.2. (virtual env) ~/myprojectdir/manage.py migrate
4.3. (virtual env) ~/myprojectdir/manage.py collectstatic

Before running the above, I will run all 'Migrating a Django app from MySQL
to PostgreSQL' steps documented in your blog first and then proceed with
the above commands in my server virtual environment.

I believe I've to run your steps in virtual environment only right?

Thanks,
~Ram

 Hello Carlos,

 The steps looks promising. We will try it and let you know.

 Our dB is originally from MySQL configured for PHP based website and
 later on we moved to Django project development. Now we planned to migrate
 the site to Postgres database running on Ubuntu for Django project.

 Thank you very much.,

Re: Django- Display PDf document in an Iframe or Pdf VIewer

[Mark Phillips]

Lucas,

I have many documents that I have uploaded to my django app. The docs are
stored in the file system, but the path is in my django model. The docs are
either pdfs or png images.

This is how I am displaying pdf images in my ModelAdmin change form:

  readonly_fields = ('get_image_3', )

def get_image_3(self, obj):
display_image = ""
if (obj.document_id):
# Get the path to the main image
doc_file_path = obj.document_id.storage_file_name.path
if obj.document_id.storage_file_name.name.endswith('pdf'):
display_image = 'http://www.adobe.com/products/acrobat/readstep2.html";>'.format(image_link =
obj.document_id.storage_file_name.url)
else:
display_image = 'Click to tag people, Ctrl-click to
tag animals'.format(document_link =
obj.document_id.storage_file_name.url, doc_id=obj.document_id.document_id,
height=settings.FACE_ADMIN_PREVIEW_HEIGHT)
return format_html(display_image)

The adobe reader renders a nice window for scrolling the pdf and changing
pages.

To display a thumbnail of the pdf on the main ModelAdmin page, I used
Pillow to grab the first page of the pdf and make a jpg thumbnail of that
page. Then use similar code from the display_image above after the else
(for displaying an image on the page in the admin).

Hope that helps!

Mark

When to use Admin model_delete/model_save and Model delete/save?

[Mark Phillips]

Just curious as to the best practices for using save/delete in Model versus
delete_model/save_model in ModelAdmin. Is one preferred over the other?

In my particular case, I have a Document model with a JSON field that holds
a bunch of metadata (name:value pairs) for Documents (photos, pdfs, etc).
The metadata is defined in other models (MetaData for names and
MetaDataValue for the value(s)), so I can change the metadata names and
values at run time.

When an existing MetaData name or value changes or is deleted, I need to
"scrub" the metadata stored in the Document model to change/delete the
metadata names/values to keep them in sync with what is defined in the
MetaData and MetaDataValue models. All these changes are done through the
Admin screens.

Would it be more appropriate to use model_save and model_delete in the
Admin or save and delete in the respective models? Functionally, it does
not matter as far as I can see. I am just wondering if there is a preferred
way, or a more "django idiomatic" way to do this.

Thanks!
Mark

Django- Display PDf document in an Iframe or Pdf VIewer

['Lucas Gärtner' via Django users]

Hello everyone!

I just signed up here, so maybe this thread is wrong in this group. 

The problem is as follows:

I need to display a PDF document in a half of a web application.
I tried it first with Iframe and now today with pdf.js.
Nothing helped. Do you have any idea? 
It is only showing the pdf, not more.

I am using django: 2.1.10 and Python 3.7.1

Hope you have some good recommendations!

Have a nice day!
Lucas

Customer specific translations

[Jani Tiainen]

I've use-case where my django app is delivered to multiple customers in
multiple languages.

Due the nature of application end users do use for certain terms their own
wording, which differ significantly from others.

For example:

"Delivery route". Some may call it "driving route". Some "route" and some
just "delivery route".

Any ideas how to handle this?

Maybe you should use ListView, not DetailView.

Re: Generic view template seems to have empty input

[山村維宏]

Sorry, I mistaked.
You can use Detail view.

DetailView pass your model data, which named "book"(because model name is
Book).
Model doesn't list.

Generic view template seems to have empty input

[Manos Zeakis]

Hi 

I have declared a model and the simple views I created are working.

Now I am trying to move to generic views. 

So I added in urls.py

path('book2//', views.DetailView.as_view(), name='detail'),

And in views.py

class DetailView(generic.DetailView):
model = Book

And the template is

{% block content %}

  book List
  {% if object_list %}
  
{% for book in object_list %}
  
{{ book.author }}
  
{% endfor %}
  
  {% else %}
There are no books in the library.
  {% endif %}   

{% endblock %}

For reference the models.py had been

class Book(models.Model):
author = models.CharField(max_length=70)

But the result is "There are no books in the library". So it seems that the 
books list is not transferred to the template to be rendered. Could you 
help me understand where I have done wrong?

Thank you

Re: Best way to organize custom admin views?

[Wim Olivier]

Hi,

I'd recommend using seperate apps for custom admin areas (1 app for each), 
and implementing a middleware that allows access to the relevant admin 
based on roles/permissions, etc.
It's simple, kept seperate from other code/apps nicely, and easy to limit 
access to different groups.

blogapp/
blogappadmin/

hrappadmin/

Wim
