URL — Routing & Navigation

Pytigon's URL system builds on Django's URL dispatcher with automation and structure that eliminates manual URL configuration for standard CRUD operations.

Automatic URL Generation

When you define a model and configure views through the developer tools, Pytigon generates URL patterns automatically. The standard pattern is:

[app_name]/table/[TableName]/[base_filter]/[filter]/[target]/[view_type]/

URL Segments Explained

Segment Purpose Example
app_name Django application name tables_demo
table/[TableName] Model/table identifier table/Album
base_filter Parent record filter (for sublists) 3 (parent ID)
filter Query filter string active=true
target Output format pdf, xlsx, json
view_type View type list, edit, add, tree

URL Resolution

Pytigon's URL pattern uses regular expression matching:

r'((?P<base_filter>[\w=*,;-]*)/|)
(?P<filter>[\w=*,;-]*)/
(?P<target>[\w_-]*)/
[_]?(?P<vtype>list|sublist|tree|get|gettree|table_action)/$'

Custom URL Definitions

For views that don't fit the standard CRUD pattern, define URL patterns in [app]/urls.py:

from django.urls import path
from . import views

urlpatterns = [
    path('custom-report/', views.CustomReportView.as_view(), name='custom_report'),
    path('api/data/', views.api_data, name='api_data'),
]

View Types and Their URLs

View Type URL Pattern Method
List .../list/ GET
Sublist .../sublist/ GET
Tree .../tree/ GET
Get (single) .../get/ GET
Add .../[param]/add/ GET + POST
Edit .../[id]/edit/ GET + POST
Delete .../[id]/delete/ GET + POST
Table Action .../table_action/ POST

Target (Output Format)

The target segment determines the output format:

Target Format Content-Type
(empty/default) HTML page text/html
pdf PDF document application/pdf
odf Open Document application/vnd.oasis.opendocument.text
xlsx Excel application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
json JSON application/json
txt Plain text text/plain
csv CSV text/csv
verXYZ HTML with suffix XYZ in template name text/html

URL Navigation in Templates

Templates use Django's {% url %} tag for reverse URL resolution:

[a href="{% url 'myapp:album_list' %}"...View Albums]
[a href="{% url 'myapp:album_edit' object.id %}"...Edit Album]

Pytigon's href_action module provides additional URL manipulation tools for constructing complex navigation paths programmatically.

Base Path Handling

Pytigon supports subdomain/deployment path prefixes automatically. The context variable base_path is always available in templates for constructing absolute URLs:

[a href="{{base_path}}myapp/table/Album/"...Albums]
?: Url ?: Url
