Re: creating project in Django

[Kelly Nicholes]

Django-admin has to be on your environments path.  Find where your 
Django-admin.oh file is and do the whole path.  python 
c:\...\Django-admin.python startproject myproject.  Maybe you forgot to 
activate your virtualenv?

Sorry about random capitalization.  Typed on my phone.

Re: Fast and Easy way to check if an instance of an Model exists in the Database

[Kelly Nicholes]

Wait-- Why aren't you using exists()?  Don't even check the pk.  
Model.query.exists() was made for this.

Re: app to record and play video

[Kelly Nicholes]

Django, as far as the front-end is concerned, has little to do with 
actually capturing the video.  This is going to be on the frontend with 
your browser.  Depending on your audience, they might not have browser web 
capture available and will have to use a browser plugin like flash or 
silverlight, as mentioned in 
http://www.html5rocks.com/en/tutorials/getusermedia/intro/.  Otherwise, 
follow that link and see if that'd suit your needs.

Re: Need good image on the fly resizing

[Kelly Nicholes]

For the problem with sorl-thumbnail not resizing to the same size as the 
others--  Are you cropping the image at all or just resizing?  If you crop, 
I don't understand how the images wouldn't be all the same size.  When I've 
used sorl, if the image is bigger than the dimensions to which I'm 
cropping/resizing, it's always spot-on.

Re: e commerce django framwork

[Kelly Nicholes]

I recommend you take a look at 
https://www.djangopackages.com/grids/g/ecommerce/.  I've used satchmo a 
couple times.  I recall setting it up having a couple snags, but nothing 
unmanageable.  Overriding the templates isn't a big deal if you understand 
the TEMPLATE_URLS setting.  I haven't customized it extensively, but for 
what I needed, it was great for me right out of the box.

I was looking for something like this for CBVs about a week ago!  I'm glad

 I might try this out!  Thanks.  This is a very common pattern, I've found,

Pattern for Ajax Forms using Django ModelForm and Class Based Views.

[Kelly Nicholes]

What's the best practice for this?  In my function based views, I'd check 
if the form is_ajax() and if so, validate the form, render_to_string it to 
a form template, and return that in a json dump along with a status code. 
 Then I check the status code to see if there are errors.  If so, I close 
the modal that the form is in, notify the user of successful addition, and 
move on.  If there are errors, I replace the form's HTML in the modal with 
the new HTML that contains the form with error messages.  This sucks 
because I have to do this for every form and for every view that I have.

Re: No module named models again

Yeah, for things like forms.py and views.py, it's best to use relative

Re: On the fly image resize

[Kelly Nicholes]

Check out sorl-thumbnail.  https://github.com/sorl/sorl-thumbnail .  This 
lets you specify the desired size in a template.and can deal with cropping. 
 It caches the results so it doesn't have to regenerate it each time.

Re: Moving a Django website to another server

[Kelly Nicholes]

If you're storing your images in your database (don't) then your db 
migration should have done it.  If you're storing the paths in the 
database, let's hope they're relative paths to the images.  You'll have to 
copy the images to your new server using the same approaches listed above. 
 One alternative is to have a separate server that serves all of your 
static media, then your paths can stay the same, regardless of which 
server(s) your database(s)/code is on.

Re: How do you extend a queryset object with another queryset as in list.extend(another_list)

[Kelly Nicholes]

You can always use itertools.chain() if you want to do it in memory. 
 Instead of doing it in memory as you've suggested, perhaps you need to 
index the account's PK so when your Items object manager queries for them, 
it can be quick.  

import itertools

list1 = [1,2,3,4]
list2 = ['a','b','c','d']

combined_list = itertools.chain(list1, list2)

Re: Storing Sorl-thumbnail created images in separate folder

[Kelly Nicholes]

It always just caches the files for me in a completely different directory.

Can't you get a queryset, like

Re: Associating Form Data with Users

[Kelly Nicholes]

Your YourModelForm is a modelform of a model.  If you're setting a
property of that model, AND YOU WANT IT TO PERSIST IN THE DATABASE,
you set the property equal to the request.user and save that object.
If you don't have a foreignkeyfield to User, there's no way you're
going to associate that model with a user and have it persist.
Setting it in memory is going to be useless (unless you use it in the
view/template immediately after you associate the user with the
model).

class YourModel(inherit from whatever the model is that you should
inherit from):
field = models.Charfield(...blahblahblah)
user = models.ForeignKeywhatever()

Then do what Thorsten said.

Re: Somebody please attend to me

[Kelly Nicholes]

This is link holds the PERFECT answer for you:
http://bit.ly/wc0psc

If you want to do it differently, try:

First you'll have to send an XMLHttpRequest (jQuery post() or get())
to your server to post a form (create a modelform with a "Comment"
model with all of the required fields.  You might want to look into
generic content types for django models).  Save the comment out
(associate it with the user from the request) in your view.  Then add
a link to do a comment (if you want you can do fancy html5 stuff with
the "editable" property on some div).  The click the link, dynamically
(use jquery) to show another form (or create it if you'd like).  When
they submit the friend comment, associate that friend comment with the
original comment (you could parse this out of the ID attribute that
you could set on the original comment) and save it just as you did the
first...  Or just look for premade things...

You could look into django's built-in comment system
https://docs.djangoproject.com/en/1.2/ref/contrib/comments/example/
Here's one called django-facebook-comments 
https://bitbucket.org/sirpengi/django-facebook-comments

You need to set the name parameter.  name="card_create_card".  Once
you do that, reference it in the {% url  %}.

Re: Django Improper Configuration

[Kelly Nicholes]

I think I had this error too when I was cloning a repo from WebFaction
to use on my local dev machine.  I ended up having to replace
WebFaction's manage.py with the one from Django.  Let me know if it
works for you!  I wish I could explain why.  Can't.
