Your MEDIA_ROOT directories are a mess? FileField save on "upload_to" directories with old/strange/temporary names decided "on the fly" and never fixed down? SmartFolderFileField is the solution! "upload_to" directory depends only on: app, model and field names. No mess, no ambiguities Obviously, in case you need a real callable for a dynamic directory name: please use it! and leave apart FixedFolderFileField Sample: from django.db import models from utilities_app.models import SmartFolderFileField class SampleModel(models.Model): sample_char_field = models.CharField(max_length=50) sample_file_field = SmartFolderFileField()
This snippet will change the field to include the placeholder in the field using the help_text attribute from the model or the form
sterm is the search term. text is the result search text. it will highlight every matched search term in search result. please define your own .yellow css class. use: {{search_result_var|highlight:search_term}}
Some INSTALLED_APPLICATIONS applications may not be critical for your website to work - for example you may only need them for development - like 'django_extensions' or 'debug_toolbar'. They needn't be installed actually for the site to work. This way you can avoid discussions with other developers if some application should be included, or is it just spam, because if they don't like it, they don't have to install it. On a production server you can leave this not installed, to avoid security concerns like a possibility to IP-spoof and see the debug toolbar.

This validator works well with FileField form fields and can validate that an uploaded file has an acceptable mimetype. Place this snippet in your app's `validators.py`. Requirements: This snippet uses [python-magic](https://github.com/ahupp/python-magic). To install: pip install python-magic Usage (in forms.py): from validators import MimetypeValidator class MyForm(forms.Form): file = forms.FileField( allow_empty_file=False, validators=[MimetypeValidator('application/pdf')], help_text="Upload a PDF file" )

Function that takes a bound form (submitted form) and returns a list of pairs of field label and user chosen value. It takes care of: 1. fields that are not filled out 2. if you want to exclude some fields from the final list 3. ChoiceField (select or radio button) 4. MultipleChoiceField (multi-select or checkboxes) Usage: if form.is_valid(): form_data = get_form_display_data(form, exclude=['captcha']) It's trivial to display the list of pairs in a template: {% for key, value in form_data %} {{ key }}: {{ value }}{% endfor %}
