Document Context is a dict fed to the Flask {{code|render_template}} function. Most of the keys in the dict are handled (with default values assigned, if not given) by a separate Python function {{code|prep_mainseq}}. We shall begin with these so-called ''Main Sequence'' keys, then we will discuss a few additional keys. [[#More render_template Arguments]] | |||

While CuneiForms and CuneiTables on each of their own can create functional pages for several purposes, most accounting and transaction records require both to be displayed and manipulated in a meaningful manner. And while it is possible for such pages to be perfectly functional by stringing stad-alone forms and tables together, the numbers of requests and database accesses are unnecessarily high.
In the CuneiFox framework, inter-related forms and tables can be linked together via the use of Document Context. Below are the key functions of Document Context:
- Control page-level permissions and operations.
- Perform a document-lock/unlock upon entering entering/exiting the page's edit mode.
- Consolidate populating request for all forms and tables on the page.
- String together page edit sequence.

Document Context is a dict fed to the Flask render_template function. Most of the keys in the dict are handled (with default values assigned, if not given) by a separate Python function prep_mainseq. We shall begin with these so-called Main Sequence keys, then we will discuss a few additional keys. #More render_template Arguments

Finally, in the last sub-section of this part, we will list a few commonly used render_template arguments that are not parts of Document Context, but are useful nonetheless.
