So right now, if the user hits submit, four modelforms will be handled in views, and models will be linked and added to the database.

AleksTK: I don't know what you mean by a blank model.

However the borrower info form is not filled out, so a blank model will be added.

I mean a model with only a primary key and all the fields null.

Since all the fields are optional.

It gets created?

Yes.

Instead I want to change my view logic to determine if all the fields are blank, and not create it.

Can you pastebin your forms?

I'm not sure how to check if all the fields are blank, except for checking them one by one.

Gladly.

maybe set it as required?

Siecje, I know I can do that. But users may not have all the information at the beginning, but still need to add the property.

And they should be able to see a list of incomplete properties, and add information to them later.

In this case, the borrower info.

I thought there would be some method with modelform that would return true if the form is empty.

I'm surprised there is not.

So isn't it doing what you want?

It creates a model that you can modify later?

Siecje, right. It creates models for all of them. But I want it to check the form for each model (except property), see if it is blank. And if it's blank, not add that model, and simply not set the foreign key for the corresponding property model.

Does that make sense?

So with the example picture I sent you.

It should make every model except the borrower model, link them to property, and add them to the database.

Because the borrower field is blank.

I just don't know an easy way of checking of all the fields in the borrower modelform are blank.

Except I guess checking each one and hardcoding the field names in the view.

You should pass an instance into each form

So if you already have a borrower pass that borrower instance into the form

Siecje, I do that on an update page.

But you

*you're looking at the add new property page.

(8:08:05 PM) AleksTK: It should make every model except the borrower model, link them to property, and add them to the database.

What is it doing?

It's making every model, and adding it to the database.

Including a borrower model, with all blank fields, which is linked to the property model.

Instead, it should detect the borrower form as blank, and not add it.

I haven't written the code to do that.

Because I'm not sure how.

Sorry if I seem thick, I'm sure this is really simple.

I'm new to Django though.

AleksTK: Try form.has_changed()

Hey, someone with celery + gevent experience here ?

Siecje, good idea.

That works.

how can i run django without a db

set DATABASES to an empty dict

Siecje, thanks.

i get an error settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

I saw that before but thought it wouldn't work for some reason.

hey all. i'm having trouble understanding the correct way to use select_related, even after reading the docs. can someone review this simple example (along with the error message i get) and perhaps steer me in the right direction? https://dpaste.de/B4HP

@ AleksTK, just noticing what you are talking and might be a bit out of context. You might be talking about the isValid() function? That checks if fields are blank/invalid.

django347, I thought that only applied to required fields.

All these fields are optional.

Also, I'm still definitely wondering about the error, it really is quite confusing to me

By the way I really appreciate this IRC channel. It helps me a lot.

django347, my error?

I already fixed everything, by using the function Siecje suggested.

Ah, yes, you are right. I didn't realize you wanted it for non required fields

Oh no, my error from earlier.

im having some issues getting my static files to load on live server

That is good, that you have everything fixed

bigDicts, I /just/ had that issue.

I couldn't figure out why static files in one app loaded but not in another.

After around 30 minutes of debugging everything, I realized I put a slash in front of the static directory.

{% static '/properties/css/test.css' %}

Instead of {% static 'properties/css/test.css' %}

i have Debug set to false, STATIC_URL and STATICFILES_DIRS defined

AleksTK: im using <link rel="stylesheet" href="static/css/main.css"/>

bigDicts, any reason you aren't using {% static %}?

And do you have {% load static %} at the top of your file?

no, im using jinja template engine not DTL so that throws an error

locally the styles load, but not on live server

Oh, hmm.

No sure.

ciderkk: product = Product.objects.select_related('productversion_set').get(id=id)

Random thoughts, have you checked to see if they are properly on the server? I.e. have you checked .com/static/file

here is a link to my test site http://www.readbeepbeep.com/

randyinthedesert, thanks for the suggestion. i tried 'product = Product.objects.select_related('productversion_set').get(id=id)' but unfortunately i got the error "Invalid field name(s) given in select_related: 'productversion_set'. Choices are: (none)"

i'm not familiar with the "_set" thing so i'll look into it and perhaps it will steer me in the right direction

django347: yes. it returns a 404 error page

Is it possible you are accidentally forwarding http://www.readbeepbeep.com/static/css/main.css to not a file?

So, in your url.py, is it possible you have a regex that grabs /static/css/main.css

so, that last one

its my urls.py file

The one that forwards to main, did you mean to do "^$"?

Indeed

I could be very wrong about this, so someone please correct me, but it certainly seems like it might be it

django347: i tried "^$" for the main url but got 500 error

not sure why this worked fine locally

My bad, you're right. I should have looked at that more carefully

do i need a url for "^static/" ??

not sure how to specify the params if so.

ciderkk: check out reverse relationships https://docs.djangoproject.com/en/1.8/topics/db...

Honestly, I'm rather new at this, so I'm not sure.

select_related only accepts field names or reverse relationship sets as args

same here lol

Out of curiosity, what does + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) return?

i have no clue..i followed the docs

I assume its appending a static url based on the settings

Probably. But, if it goes in order, then your r"" is going to override it

So maybe you could try adding the r"" after you add the static url?

(To clarify, the regex r"" matches all unmatched strings up to that point)

sigh. This reverse foreign key relationship thingy works fine in the shell but not in the view

Also, another clarification, bigDicts, you can just change the [] + static to static + []

Oh wait, I found it

This helper function works only in debug mode and only if the given prefix is local (e.g. /static/) and not a URL (e.g. http://static.example.com/). Also this helper function only serves the actual STATIC_ROOT folder; it doesn’t perform static files discovery like django.contrib.staticfiles.

So that's why it wasn't working in production, but it was working in debug

aha!

geez..so i guess i need to move the static folder to the root dir
