django-uni-form (django-uni-form)

Django forms are easily rendered as tables, paragraphs, and unordered lists. However, elegantly rendered div based forms is something you have to do by hand. The purpose of this application is to provide a simple tag and/or filter that lets you quickly render forms in a div format.

Uni-form has been selected as the base model for the design of the forms.

Warning: django-uni-form 0.8 and higher renders django.form.field labels with the 'safe' filter. If you have user generated form field labels you should take this into consideration.

Note: django-uni-form 0.8 and higher lays out the HTML for the uni_form tag differently than previous versions. The errorMsg div is now outside the fieldset as it should be.

Note: django-uni-form 0.7 and higher breaks backwards compatibility with previous versions of django-uni-form. All you have to do is update templates that call on the django-uni-form template tag from:

{% load uni_form %}

To:

{% load uni_form_tags %}

Installation

Dependencies

• JQuery

Installing django-uni-form

Install into your python path using pip or easy_install:

pip install django-uni-form
easy_install django-uni-form

Add 'uni_form' to your INSTALLED_APPS in settings.py:

INSTALLED_APPS = (
    ...
    'uni_form',
    )

Depending on your setup, you may need to copy the media files to your local media folder:

cp -r <location-of-django-uni-form>/uni_form/media/uni_form <directory-for-my-project's-media-files>

Displaying the media files

First, make sure you're linking to a copy of jQuery. It's recommended that you use the version hosted on Google's servers since the user's browser might already have it cached. (You can get the url for the latest version of jQuery at http://scriptsrc.net/.) But there are some cases in which you'll want to host jQuery yourself, such as if you're doing development offline:

<script src="{{ MEDIA_URL }}js/jquery.js" type="text/javascript"></script>

Beyond jQuery, django-uni-form requires three media files. You can see how we call them by looking in the templates/includes.html file. You can call those files in several ways.

1. The best way is probably to copy this HTML into your templates. This allows you to make use of the CSS compressors that have been created by the Django community (http://www.djangopackages.com/grids/g/asset-managers/). Here's the HTML:

   <link rel="stylesheet" href="{{ MEDIA_URL }}uni_form/uni-form.css" type="text/css" />
   <link rel="stylesheet" href="{{ MEDIA_URL }}uni_form/default.uni-form.css" type="text/css" />
   <!-- note that there's also blue.uni-form.css and dark.uni-form.css available if you want to try changing defaults up -->
   <script src="{{ MEDIA_URL }}uni_form/uni-form.jquery.js" type="text/javascript"></script>
   

2. Another way is to use Django's built-in includes template tag:

   {% include "uni_form/includes.html" %}
   

3. A third way is to use the django-uni-form uni_form_setup template tag. Note that you'll need some additional setup for this:

   {% uni_form_setup %}
   

If you want to take advantage of the uni_form_setup tag, then you'll need to make sure 'django.core.context_processors.request' is in the TEMPLATE_CONTEXT_PROCESSORS tuple in your settings.py file:

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'django.core.context_processors.request',
    )

Customizations on '*' required fields (optional)

If you don't like the use of '*' (asterisk) to denote required fields you can simply overrride the django-uni-form field.html. In your Django project's templates directory create a new directory called uni_form. Copy the django-uni-form field.html file to that directory and make the desired changes. For example:

cd ~/<my-projects>/<my-awesome-django-project>/templates/
mkdir uni_form
cd uni_form/
cp <my-site-packages>/Django-uni-form/uni_form/templates/uni_form/field.html .

Now you could change the asterisk to any other character, an image icon, or whatever else you want.

Using Uni-Form strict fields

django-uni-form implements form fields in html differently than the standard Uni-Form. If you want to adhere to the strict definition of django-uni-form replace the field.html file with field.strict.html. You can just follow these instructions:

cd ~/<my-projects>/<my-awesome-django-project>/templates/
mkdir uni_form
cd uni_form/
cp <my-site-packages>/Django-uni-form/uni_form/templates/field.strict.html field.html

Usage

Using the django-uni-form filter (Easy and fun!)

1. Add {% load uni_form_tags %} to the template that calls your form.

2. Append your form call with the as_uni_form filter:

   {{ my_form|as_uni_form }}
   

3. Add the class of 'uniForm' to your form. Example:

   <form action="" method="post" class="uniForm">
   

4. Refresh and enjoy!

Using the django-uni-form templatetag in your view (Intermediate)

1. In your views.py add the following after field definitions:

   from django.shortcuts import render_to_response
   
   from uni_form.helpers import FormHelper, Submit, Reset
   from my_project.forms.MyForm
   
   def my_view(request):
   
       # Create the form
       form = MyForm()
   
       # create a formHelper
       helper = FormHelper()
   
       # Add in a class and id
       helper.form_id = 'this-form-rocks'
       helper.form_class = 'search'
   
       # add in a submit and reset button
       submit = Submit('search','search this site')
       helper.add_input(submit)
       reset = Reset('reset','reset button')
       helper.add_input(reset)
   
       # create the response dictionary
       response_dictionary = {'form':form, 'helper': helper}
   
       return render_to_response('my_template.html', response_dictionary)
   

2. In your template do the following:

   {% load uni_form_tags %}
   
   {% uni_form form helper %}
   

Using the django-uni-form templatetag in your form class (Intermediate)

1. In your form class add the following after field definitions:

   from uni_form.helpers import FormHelper, Submit, Reset
   
   class MyForm(forms.Form):
       title = forms.CharField(label=_("Title"), max_length=30, widget=forms.TextInput())
   
       # Attach a formHelper to your forms class.
       helper = FormHelper()
   
       # Add in a class and id
       helper.form_id = 'this-form-rocks'
       helper.form_class = 'search'
   
       # add in a submit and reset button
       submit = Submit('search','search this site')
       helper.add_input(submit)
       reset = Reset('reset','reset button')
       helper.add_input(reset)
   

2. In your template do the following:

   {% load uni_form_tags %}
   {% with form.helper as helper %}
       {% uni_form form helper %}
   {% endwith %}
   

Using the django-uni-form templatetag to change action/method (Intermediate)

1. In your form class add the following after field definitions:

   from uni_form.helpers import FormHelper, Submit
   
   class MyForm(forms.Form):
       title = forms.CharField(label=_("Title"), max_length=30, widget=forms.TextInput())
   
       # Attach a formHelper to your forms class.
       helper = FormHelper()
   
       # Change the form and method
       helper.form_action = 'my-url-name-defined-in-url-conf'
       helper.form_method = 'GET' # Only GET and POST are legal
   
       # add in a submit and reset button
       submit = Submit('search','search this site')
       helper.add_input(submit)
   

2. In your template do the following:

   {% load uni_form_tags %}
   {% with form.helper as helper %}
       {% uni_form form helper %}
   {% endwith %}
   

Adding a layout to your form class (Intermediate)

Uniform helpers can use layout objects. A layout can consist of fieldsets, rows, columns, HTML and fields. A simple Example:

from django import forms

from uni_form.helpers import FormHelper, Submit, Reset
from uni_form.helpers import Layout, Fieldset, Row, HTML

class LayoutTestForm(forms.Form):

    is_company = forms.CharField(label="company", required=False, widget=forms.CheckboxInput())
    email = forms.CharField(label="email", max_length=30, required=True, widget=forms.TextInput())
    password1 = forms.CharField(label="password", max_length=30, required=True, widget=forms.PasswordInput())
    password2 = forms.CharField(label="re-enter password", max_length=30, required=True, widget=forms.PasswordInput())
    first_name = forms.CharField(label="first name", max_length=30, required=True, widget=forms.TextInput())
    last_name = forms.CharField(label="last name", max_length=30, required=True, widget=forms.TextInput())

    # Attach a formHelper to your forms class.
    helper = FormHelper()

    # Create some HTML that you want in the page.
    # Yes, in real life your CSS would be cached, but this is just a simple example.
    style = """
    <style>
        .formRow {
            color: red;
        }
    </style>

    """
    # create the layout object
    layout = Layout(
                    # first fieldset shows the company
                    Fieldset('', 'is_company'),

                    # second fieldset shows the contact info
                    Fieldset('Contact details',
                            HTML(style),
                            'email',
                            Row('password1','password2'),
                            'first_name',
                            'last_name',
                             )
                    )

    helper.add_layout(layout)

    submit = Submit('add','Add this contact')
    helper.add_input(submit)

Then, just like in the previous example, add the following to your template:

{% load uni_form_tags %}
{% with form.helper as helper %}
    {% uni_form form helper %}
{% endwith %}

This allows you to group fields in fieldsets, or rows or columns or add HTML between fields etc.
