Interesting. I never thought about doing a pip install of an application. I'm 
going to have to digest that one. 

Thanks

The project django-wiki is not a django project, it is a django app. You
include the app in your project.
The settings file in the install document is your settings file from your
django project.

Re: django vue javascript integration

[Sithembewena L. Dube]

The issue here appears to be that OP's browser cannot load the .js file as
specified in the resource path. I would agree with Wira about checking what
the path is and ensuring that the .js file is in the correct location.

Kind regards,

Re: How to override the ModelAdmin "change" form ?

[Mike Dewhirst]

On 2/03/2019 2:08 am, karim.at...@gmail.com wrote:

Hi Mike,

I tried what you wrote by overriding the *self.change_form_template* 
but the form does not appear.
Would you please provide me the content of your model admin 
*billing_payment_view ?*


Sure. I recently asked for assistance here and posted most of the code ...

https://groups.google.com/forum/#!topic/django-users/809HBmPa9vk

You are right, my application is different. My template contains a 
script provided by Stripe which calls their API to collect a credit card 
payment. But overall it isn't much different than any other template 
called by any other view. The view just takes a different path depending 
on whether it is a POST or a GET request. My view looks complex because 
when the user clicks [Pay now] it happens in the Stripe js embedded in 
the template and the Stripe API - in turn - hits my view with the actual 
POST containing the result of the credit card transaction. I had to seed 
the form/template with hidden data so it travelled across the Stripe 
boundary and back to me so I could complete the processing. If you can 
see past that complication it should be clear that I'm using the form to 
clean the data and the view to interface with the ORM/database.


It is working well for me now and I'm in the middle of writing unit tests.

Good luck



Thanks.

Hi,

I'm currently struggling with a custom ModelAdmin.


Karim

I haven't tried to fully understand your use case. However, this
is what I think your process could be if you do not wish to ajax
it ...

1. Override the model save() method to call a model method which
detects your trigger scenario and calls the code you wish to
execute to collect all the data you wish to display. This might be
in the parent model or the m2m 'through' model. Unlikely to be in
the child model.

2. Write a Form to reveal the data you wish to display. It
probably needs to be a ModelForm

3. Write a template for the data including any hidden fields for
object pks and additionally consider calling {{ block.super }} to
display inherited stuff if you are extending another template and
using the same block. When I first started to work all this out I
was able to get my form to appear at the top of the ModelAdmin
form using block.super and spent a bit of time hiding the big red
[Delete] button because it was too close to my big blue [Pay now]
button. However, as I got deeper into it I somehow lost that and
never got it back. I was so pleased with getting it working
eventually that I persuaded myself I didn't really want it on the
same page anyway. Your mileage may vary :) I think you need to
hard-code the form in the ModelAdmin to get it appearing above
everything else.

4. Write any necessary urls

5. Write a view to manipulate your data, based on the request and
your form

6. Get the Admin to display it on demand. The first line of the
change_view() method below initialises the ModelAdmin to do
absolutely nothing different than usual. Nothing will happen
unless the trigger is detected. Then finally call to super to
resume the normal course of events when your code is complete.
What follows is my own recent experience. The comments should tell
you more than the code

def change_view(self, request, object_id, form_url='', extra_context=None):

     """ self = SubstanceAdmin
 request = wsgi request object
 object_id = substance
 form_url = no idea!
 extra_context = dict of apps, models, admin_urls and permissions

 https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#django  
.
 contrib.admin.ModelAdmin.change_view

     """
 # Let the ModelAdmin resume normal operations with its own template
 self.change_form_template = None
 # queryset of m2m records from the 'through' table
 ingredients = 
Substance_Ingredients.objects.filter(substance_id=object_id)
 subscription = None
 for sm2mi in ingredients:
 # sm2mi.fee_payable() is the detector which triggers the process
 payable, fee_type = sm2mi.fee_payable()  # eg., True, PAID_DATA
 if payable:
 # generate a subscription record with blank token field or
 # if one exists with a non-blank token, return None
 subscription = billing_subscribe(sm2mi, fee_type)
 if subscription:# collect money for the owner
 # switch the ModelAdmin to the new template
 self.change_form_template = 'payment.html'
 # assemble all the necessary data for the view

Re: Why are foreign keys rewritten when adding related_name?

Doing copy-paste always lead to indentation fault.Try to copy the code on 
any editor and then indent 2nd statement by 4 or 8 space indent .

Issue with ManyToMany Relations

[Julio Cojom]

I'm writting 2 models with ManyToMany Relations, first I make a model to 
list all my requirements

class Requirements(models.Model):
requirement = models.CharField(max_length=150)
def __str__(self):
return self.requirement

So in this example my list of requirements will be:

   - Personal ID
   - Letter from your boss 
   - Last degree obtained
   - Photography
   
Now I make custom list from different scenarios, since not all jobs require 
the same documents, my model will be: 

class RequirementsList(models.Model):
job= models.ForeignKey(Jobs, on_delete=models.DO_NOTHING)
requirements= models.ManyToManyField(Requirements)

def __str__(self):
return str(self.job)

Now I can pick some of my requeriments and make custom lists from each job 
or position avaliable.

Last, I make my 3rd model , with a relation between RequirementList and File

class FileDetail(models.Model):
file= models.ForeignKey(File, on_delete=models.DO_NOTHING)
job = models.ForeignKey(Jobs, on_delete=models.DO_NOTHING, blank=True, 
null=True)
requeriments = models.ManyToManyField(RequirementsList)

def __str__(self):
return self.file

So I need my requirement list to filter what requirements who has to be in 
my file, but this only give to me in requirements a list of lists instead 
of requirements in the list.

I been reading the docs and found the "through" parameter but I can't make 
it work.

Somone has a clue of what I'm doing wrong?

Thanks!

django vue javascript integration

[Tomas Garijo]

Hello group,

I have a huge problems to integrate a vue javascript file in one template, only 
for testing, I'm searching on google but unfortuny I can't find anything.
I have a simple html file and I want to load a code that is in other file, of 
course this files is a *.js file

The best is attach some file to see the problem

You can see in the html file,  there is some comment code this is a test to see 
if the javascript code works fine, and this works fine.
But when this javascript code put in other file and load from html file (I'm 
not sure this will be true) the code doesn't work fine. 


Kinds Regards

Re: Problems with first program

[Sam W]

The error is very clear "IndentationError: expected an indented block" Use 
PyCharm IDE OR Visual Studio Code.
Also, never use Keyboard Spacebar for indentation , always use Tab for 
indentation. TO solve your problem take the question_text to the beginning 
of the line then hit the Tab once.

Re: How to override the ModelAdmin "change" form ?

[karim . atiki]

Hi Mike,

I tried what you wrote by overriding the *self.change_form_template* but 
the form does not appear.
Would you please provide me the content of your model admin  
*billing_payment_view 
?*

Thanks.

Karim

Hi,

You can look here:

Models in admin view

[raghav b]

I have created two apps with the name candidate and another training. In the 
Django admin I want to create trainings and add candidates to that. I have 
created candidate and training and registered in the admin view. But for the 
last part I want to add multiple candidates into a training from admin view. 
How can I do this? Please help.

Hi,

A good starting point is Django Girls tutorial. It covers basic Python and
Django with proper workflow and tool support and even deployment.

Re: How to override the ModelAdmin "change" form ?

[karim . atiki]

Hi Mike,

Thanks a lot for your feedback.
Your situation is quiet different from mine, BUT the way you override 
change_view and the related template will certainly help me to achieve what 
I need.
...and getting rid of dirty and unnecessary ajax calls.

I keep you posted.

Thx.

Karim
