Generic EAV-style table creation in the user's hands
Project description
django_userdefinedtables
This application is intended to be used as a way for an end user to define their own database tables.
It is loosely inspired by the way SharePoint lists work.

pip install django_userdefinedtables
userdefinedtables
should then added to the APPS
list in the Django settings.
Use
Models
The models which are available for use are:
Organizational
- List: Akin to a table in a relational database.
- Column: Akin to a column/attribute in a relational database. The naked Column model should not be used, as it is the parent in a multi-table inheritance scheme used to simplify querying for instances of the various column models.
- Row: Akin to a row in a relational database. Manages order and membership of data entries.
- Entry: Like, Column, utilizes multi-table inheritance for simplified querying.
Data Type
- SingleLineOfTextColumn: brief text field. Corresponding value utilizes Django CharField.
- MultipleLineTextColumn: longer length field. Corresponding value utilizes Django TextField.
- ChoiceColumn: option among several user-defined choices. Supported by the Choice model, which captures the actual choices available.
- NumberColumn: A column which allows for entry of a decimal number. Supported by NumericalColumn abstract model, which Utilizes Django DecimalField.
- CurrencyColumn: defines a currency field. Set apart from the NumberColumn in order to support formatting, but is otherwise identical. NOTE: This is possibly unnecessarily redundant to NumberColumn and may be removed in the future.
- DateTimeColumn: defines a datetime field. Corresponding value utilizes Django DateTimeField.
- BinaryColumnEntry: defines a binary field. Corresponding value utilizes Django BooleanField.
- PictureColumn: defines a picture field. Corresponding value utilizes Django ImageField.
- LookupColumn: defines a way for end users to specify a reference to a value in another column. Utilizes several foreign key relationships.
- URLColumn: defines a url field. Corresponding value utilizes Django URLField.

Generally, these entries are self-explanatory, given an understanding of the Data Type models.
- SingleLineOfTextColumnEntry
- MultipleLineTextColumnEntry
- ChoiceEntry
- NumberEntry
- CurrencyEntry
- DateTimeColumnEntry
- BinaryColumnEntry
- LookupColumnEntry
- URLColumnEntry
