-InvenTree Modal Forms
-=====================
-
-.. toctree::
-   :titlesonly:
-   :maxdepth: 2
-   :caption: Modal Forms
-   :hidden:
-
-
-The InvenTree web interface uses modal forms for user input. InvenTree defines a wrapper layer around the Django form classes to provide a mechanism for retrieving and rendering forms via jQuery and AJAX.
-
-.. image:: _static/img/modal_form.png
-
-Forms are rendered to a Bootstrap modal window, allowing in-page data input and live page updating.
-
-Crispy Forms
-------------
-
-Django provides native form rendering tools which are very powerful, allowing form rendering, input validation, and display of error messages for each field.
-
-InvenTree makes use of the `django-crispy-forms <https://github.com/django-crispy-forms/django-crispy-forms>`_ extension to reduce the amount of boilerplate required to convert a Django model to a HTML form.
-
-Form Rendering
---------------
-
-The InvenTree front-end web interface is implemented using jQuery and Bootstrap. Forms are rendered using Django `class-based forms <https://docs.djangoproject.com/en/2.2/topics/class-based-views/generic-editing/>`_ using standard Django methods. 
-
-The main point of difference is that instead of rendering a HTTP response (and displaying a static form page) form data are requested via AJAX, and the form contents are injected into the modal window.
-
-A set of javascript/jQuery functions handle the client/server interactions, and manage GET and POST requests.
-
-Sequence of Events
-------------------
-
-#. User presses a button or other element which initiates form loading
-#. jQuery function sends AJAX GET request to InvenTree server, requesting form at a specified URL
-#. Django renders form (according to specific model/view rules)
-#. Django returns rendered form as a JSON object
-#. Client displays the modal window and injects the form contents into the modal
-#. User fills in form data, presses the 'Submit' button
-#. Client sends the completed form to server via POST
-#. Django backend handles POST request, specifically determines if the form is valid
-#. Return a JSON object containing status of form validity
-  * If the form is valid, return (at minimum) ``{form_valid: true}``. Client will close the modal.
-  * If the form is invalid, re-render the form and send back to the client. Process repeats
-
-At the end of this process (i.e. after successful processing of the form) the client closes the modal and runs any optional post-processes (depending on the implementation).
-
-Further Reading
----------------
-
-For a better understanding of the modal form architecture, refer to the relevant source files:
-
-**Server Side:** Refer to ``./InvenTree/InvenTree/views.py`` for AJAXified Django Views
-
-**Client Side:** Refer to ``./InvenTree/static/script/inventree/modals.js`` for client-side javascript

-The documentation found here is provided to be useful for developers working on the InvenTree codebase. User documentation can be found on the `InvenTree website <https://inventree.github.io>`_.
-
-Documentation for the Python modules is auto-generated from the `InvenTree codebase <https://github.com/InvenTree/InvenTree>`_.
-
-Code Structure
---------------
-
-**Backend**
-
-InvenTree is developed using the `django web framework <https://www.djangoproject.com/>`_, a powerful toolkit for making web applications in Python.
-
-The database management code and business logic is written in Python 3. Core functionality is separated into individual modules (or *apps* using the django nomenclature).
-
-Each *app* is located in a separate directory under InvenTree. Each *app* contains python modules named according to the standard django configuration.
-
-**Frontend**
-
-The web frontend rendered using a mixture of technologies.
-
-Base HTML code is rendered using the `django templating language <https://docs.djangoproject.com/en/2.2/topics/templates/>`_ which provides low-level access to the underlying database models.
-
-jQuery is also used to implement front-end logic, and desponse to user input. A REST API is provided to facilitate client-server communication.

-REST API
-========

-   :caption: REST API
-   :hidden:
-
-InvenTree provides a REST API which serves data to the web client and also provides data access to third-party applications. The REST API is implemented using the `Django REST framework (DRF) <https://www.django-rest-framework.org/>`_ which provides the following features out of the box:
-
-* AJAX REST API
-* Web-browseable REST
-* User authentication 
-* Database model serialization and validation
-
-API Access
-----------
-
-The API is accessible from the root URL ``/api/``. It requires user authentication.
-
-* Requesting data via AJAX query will return regular JSON objects. 
-* Directing a browser to the API endpoints provides a web-browsable interface
-
-.. image:: _static/img/api_http.png
-
-API Documentation
------------------
-
-API documentation is provided by DRF autodoc tools, and is available for browsing at ``/api-doc/``
-
-.. image:: _static/img/api_doc.png
-
-API Code
---------
-
-Javascript/jQuery code for interacting with the server via the REST API can be found under ``InvenTree/static/script/InvenTree``.
-
-Python interface
-----------------
-
-A Python library for interacting with the InvenTree API is provided on `GitHub <https://github.com/inventree/inventree-python>`_

-================
-

-   :caption: Tables
-   :hidden:
-
-InvenTree uses `Bootstrap Table <https://bootstrap-table.com/>`_ to manage tabulated data in the web front-end. The ability to tabulate data from read via an AJAX request allows tables to be updated on-the-fly (without a full page reload).
-
-Bootstrap Table also provides integrated tools for table searching, filtering, and advanced rendering.
-
-Frontend code for table functionality can be found at ``InvenTree/static/script/inventree/tables.js``.

-InvenTree supports multi-language translation using the `Django Translation Framework <https://docs.djangoproject.com/en/2.2/topics/i18n/translation/>`_
-
-Translation strings are located in the `InvenTree/locales/` directory, and translation files can be easily added here.
-
-To set the default language, change the `language` setting in the `config.yaml` settings file.
-
-To recompile the translation files (after adding new translation strings), run the command ``make translate`` from the root directory.
