Re: passing url variables to views

Yeah

In your view you can access it by kwargs.get('user_del')

Hi,

The URL you are calling is wrong..

You should call it like http://127.0.0.1:8000/my_app/run_delete/ccc_ccc***a_b***/

No need to pass it as an query parameter.

and i want to be able to get the string ccc_ccc***a_b***

my url pattern is:
url(r'^run_delete/(?P<user_del>\w+)/$', views.run_delete, name='run_delete')
but it looks like is not catching it, i am missing something? i am using django 1.9

thanks guys

Re: DjangoCon Philly July 17-22. See you there?...

Register now to attend.

Or sign up to be a speaker and attend for free. There's a team
of speaker mentors if you have good info to share but are not
comfortable speaking to a large crowd. They can help you with
proposing, preparing and presenting your talk.

Or sign up as a volunteer like me to:
- Review talks and tutorials
- Spread the word
- Work on the website
- Run sessions, helping the speaker and attendees with logistics
- Man the registration desk
- Stuff swag bags

For those of you new to Django, here's what I like about it:
- MVC Framework (models, templates, views)
- ORM, DB migrations, syncdb, inspectdb
- Makes simple things easy, and complex things possible
- Automatic data validation
- Automated regression tests
- Middleware
- VERY friendly and helpful user community

See you at DjangoCon?

I am surprised this feature is not implemented yet, at the moment when we create a new model three permissions are created automatically:
add_permission
change_permission
delete_permission
We really missing the view_permission here, when we want staff to be able to see the content but not being able to modify it. Searching a bit, you can find many different implementations to achieve this, but all of them are extending django.contrib.admin.ModelAdmin. Having so many people rewriting these methods in my opinion is a clear sign that this feature should be part of the core.

amount = models.DecimalField(max_digits=12, decimal_places=2, default='0.00')

def __str__(self):
return self.entity

Since it's not an accounting app i have to only store data from a monthly statement report, my question here is how can i make a form that brings all accounts for a statement in a column and helps me introduce its corresponding amount in other column. My Account model really needs better logic for the account "order" or "number" part. For comparison purposes every instance of FinancialStatement() needs to hold a date representing the date when the statement was published. And that's my problem.

Hope you can help me.

Re: Looking for a good Django Forum

Me too - I'm looking for something simple; I have only looked at packages that were updated in 2016, so far I have examined:

    Pybbm - I tried this - the templates, views and models were complicated and hard to customize though the documentation was good. I may go back to this.
    Spirit - the file structure put me off. it seems needlessly complicated with several apps and the templates stored in different directories. I will try this next.
Machina and Misago both say not to use in production .

    I am going to try lbforum now.

Hi all,

Anyone know of a good forum that integrates nicely with django? Specifically both the Forum and django app should use the same userbase. Also something that is easy to integrate and theme.

I have been looking at both LBForum and DjangoBB.

Interested to hear from those who have actually implemented it.

Re: Django websites for study and improvement

You can get many django based applications from github.

https://github.com/mayan-edms/mayan-edms/

https://github.com/stephenmcd/cartridge

You can also refer

https://github.com/rosarior/awesome-django

Even though you are not interested in django internals.. this might be helpful

You should see the proper results, but for each individual request, not for the server process as a whole.

If you need sequential processing then you will have to use locks, either at the OS level or some shared resource (like the database).

Also, the RequestContext is meant for the render() function. If you just want to access request.GET then you can do it directly (request is passed in as the first parameter to your view func). You also don't need to pre-assign qList and cd, as long as they are assigned before they are accessed you are OK.

That would certainly be odd behavior, although I'm not exactly sure what you mean. Can you post the output that you're seeing and the view in question?

Re: passing url variables to views

Hi,

The URL you are calling is wrong..

You should call it like http://127.0.0.1:8000/my_app/run_delete/ccc_ccc***a_b***/

No need to pass it as an query parameter.

my url pattern is:
url(r'^run_delete/(?P<user_del>\w+)/$', views.run_delete, name='run_delete')
but it looks like is not catching it, i am missing something? i am using django 1.9

how to set null and empty value in parent field

A null value and an empty value are two separate and different things (None != ''). DRF will exclude 'parent' from the serialized data if it is not included in your input data and you have no default= in your serializer definition.

If I understand you right, you want a parent=None key-value pair in your serializer output, even if one isn't provided by the model you are serializing. In that case, I believe all you need to do is add 'default=None' to your 'parent' field in your serializer.

            return render(request, 'temp.html', context)

    else:
        form = SearchForm()
        return render_to_response('search_form.html', {'form': form})
Thanks
