A Django app which adds a ShortTextField model field, whichis like a TextField in the database and like a CharField informs.

Short Text Field for Django

A very simple Django app that adds a ShortTextField model field class, which is treated like a TextField in the database (i.e. the data is stored in the database with the text rather than the varchar type, and the developer does not need to specify a max_length), but like a CharField in forms (i.e. it uses a single-line input). This is ideal for PostgreSQL, which recommends the 'text' type in a wider variety of circumstances than other commonly-used database backends (see the [PostgreSQL docs] (https://www.postgresql.org/docs/9.1/static/datatype-character.html)).

Usage

1. Add 'short_text_field' to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...
         'short_text_field',
   ]
   

2. Add a ShortTextField to a model like this:

   from short_text_field.models import ShortTextField
   
   ...
   
     class ExampleModel(models.Model):
           ...
           example_field = ShortTextField
   

3. A model with a ShortTextField should be registered in the admin site using short_text_field.admin.ModelAdmin.

   admin.site.register(ExampleModel, short_text_field.admin.ModelAdmin)
   

   A subclass of this class will also work:

   class ExampleModelAdmin(short_text_field.admin.ModelAdmin):
       model = ExampleModel
       ...
   
   admin.site.register(ExampleModel, ExampleModelAdmin)
   

   If you have a hierarchy of ModelAdmin subclasses, you can still incorporate short_text_field.admin.ModelAdmin easily as a mixin:

   class ExampleModelAdmin2(short_text_field.admin.ModelAdmin, ExampleModelAdmin1):
       model = ExampleModel
       ...
   
   admin.site.register(ExampleModel, ExampleModelAdmin)
   

   You can also use a subclass of short_text_field.admin.AdminSite for the site, which will make short_text_field.admin.ModelAdmin the default ModelAdmin subclass to use for registering. In the simplest case, you can just set the default_site attribute of the AdminConfig class and then register all of your models in the normal way:

   from django.contrib.admin import apps
   import short_text_field.admin.AdminSite
   
   ...
   
   class ExampleAdminConfig(apps.AdminConfig):
       ...
       default_site = short_text_field.admin.AdminSite
