Re: How to check if user is already in user database?

Also, you can do a try/catch, but I don't really like this method, personally: try: User.objects.get(username=username) except User.DoesNotExist: # user didn't exist in database. On Fri, Jan 16, 2015 at 9:16 AM, Mark Furbee <markfur...@gmail.com> wrote: > Yes,

Re: How to check if user is already in user database?

Yes, that link will cover the basics... Here's a couple ways to find out if a query returns any records: User.objects.filter(username=username).exists() # .exists() returns boolean if records are found. User.objects.filter(username=username).count() != 0 # .count() returns number of

Re: (1364, "Field 'id' doesn't have a default value") - mysql issue?

You say you imported the database. Did you use syncdb to set up the tables? It sounds like your comment_id field in MySQL is not set as an auto-incrementing primary key field. Do you have access to that MySQL database to check, and or update that field definition? On Wed, Apr 9, 2014 at 2:42 PM,

I see. I don't understand how this works: {{ itens.instance.idproduto.codigobarra }} when this doesn't: {{ itens.instance.idproduto.idmercadoria.referencia }} Can you post your template code? On Fri, Aug 23, 2013 at 10:13 AM, Fellipe Henrique wrote: > form.instance is

Re: I really about to give up Django

Are you sure the idmercadoria is not None on that idproduto record? {{ form.instance.idproduto.**idmercadoria }} Does this display anything? How about {{ form.instance.idproduto }}? If these don't display, verify the records in your database. In Django templates, if something is None or does not

Are your "nome" and "idade" fields displaying? If so, {{ form.instance.brinq.descricao }} should display the descricao field of the brinq object associated with that Filhos instance bound to the form in the formset. On Thu, Aug 22, 2013 at 9:24 AM, Fellipe Henrique wrote: >

Try dropping the .value from referencia. Like {{ form.instance.idproduto.idmercadoria.referencia }}. Does this work? On Thu, Aug 22, 2013 at 9:35 AM, Fellipe Henrique wrote: > I tried again.. and work if I have just 1 FK, if I have more then one, > doesn't work, like this: >

Re: 'url' template tag throws and error after upgrading to 1.4

It would appear to me that your missing the path to django in your environment. When you upgraded did you also upgrade to another version of Python, perhaps? Is the dist-packages/site-packages django folder in the same place it was? On Thu, Apr 4, 2013 at 3:58 PM, Bastian

Re: can someone rewrite this line please

Not sure if you need the json.large to be compiled or if that should be part of the string. The biggest issue was you had a single-quote before onmouseover. After that, you have to escape the single-quote before \',LEFT, true, OFFSETY, -250, OFFSETX, 0, WIDTH, 800)\" target=\"_blank\">'; FYI: if

It means, don't use the "decorator" @login_required above your login view. Your login view cannot require a login, because you'd never get to log in. Chicken and egg. On Tue, Jan 17, 2012 at 2:34 PM, coded kid wrote: > > > Thorsten Sanders wrote: > > With using > > > >

Re: Relation not found error while dealing with foreign keys and forms

Good Morning Tabitha. Actually, do you have a model for StaffForm? That is the object being instantiated and then causing the error. If there is no nics group reference field in the StaffForm object, it may raise this error. Also, do you have this running in a view/template? Do you have a real

Re: Set of choices of which several can be chosen without using a ManyToManyField

As alluded to previously, the most "straightforward way to use a set of choices of which several can be chosen" IS to use a ManyToManyField. The syntax is slightly different, but ManyToManyFields are really easy to use with Django. Do not reinvent the wheel in this case. Thanks, M
