Quick Decision: Which Page Type?

WHAT do you need?
├── Static content page (About, Terms)     → Web Page DocType or www/ HTML
├── Data entry by external users           → Web Form
├── List of records visible on website     → has_web_view on DocType
├── Blog / news articles                   → Blog Post + Blog Category
├── Custom app with sidebar/toolbar        → Custom Portal Page (www/)
└── Dynamic route with parameters          → website_route_rules in hooks.py

See references/decision-tree.md for the complete decision tree.

Workflow 1: Create a Portal Page (www/)

Portal pages live in your app's www/ directory. The file name becomes the URL route.

• Create myapp/www/custom_page.html:

{% extends "templates/web.html" %}
{% block page_content %}
<h1>{{ title }}</h1>
<div>{{ content }}</div>
{% endblock %}

• Create matching controller myapp/www/custom_page.py:

import frappe

def get_context(context):
    context.title = "My Custom Page"
    context.content = "Hello World"
    context.no_cache = 1  # ALWAYS set for dynamic content

• Result: page available at /custom_page

File types auto-loaded: .html (template), .py (controller), .css (styles), .js (scripts).

Subdirectory pattern — for nested routes:

myapp/www/
├── services/
│   ├── index.html        → /services
│   ├── index.py
│   ├── consulting.html   → /services/consulting
│   └── consulting.py

Context Variables Reference

| Key | Type | Effect |

|-----|------|--------|

| title | str | Page title and browser tab |

| no_cache | bool | Disable page caching |

| no_header | bool | Hide the page header |

| no_breadcrumbs | bool | Remove breadcrumbs |

| add_breadcrumbs | bool | Auto-generate from folder structure |

| show_sidebar | bool | Display web sidebar |

| sitemap | int | 0 = exclude from sitemap, 1 = include |

| metatags | dict | SEO meta tags (see Workflow 7) |

Rule: ALWAYS set no_cache = 1 for pages with user-specific or frequently changing content.

Workflow 2: Create a Web Form

Web Forms let external users submit data that creates Frappe documents.

• Navigate to Web Form list → New Web Form
• Set Title, select target DocType, set Route (URL slug)
• Add fields — ALWAYS match fieldname to the target DocType field names
• Configure access:
• Login Required: uncheck for guest submissions
• Allow Edit: let users edit their submissions
• Allow Multiple: let users submit more than once
• Save and publish

Guest Submissions

ALLOWING guest submissions?
├── YES → Uncheck "Login Required"
│        → Set "Guest Title" for the submission form
│        → ALWAYS add rate limiting in site_config:
│           "rate_limit": {"web_form": "5/hour"}
│        → ALWAYS validate server-side (guests can bypass JS)
└── NO  → Keep "Login Required" checked (default)

Web Form Custom Script (Client)

frappe.web_form.on("after_load", function() {
    // Runs after form loads in browser
});

frappe.web_form.on("before_submit", function() {
    // Validate before submission — return false to cancel
    let val = frappe.web_form.get_value("email");
    if (!val) {
        frappe.throw("Email is required");
        return false;
    }
});

frappe.web_form.on("after_submit", function() {
    // Redirect or show message after success
    window.location.href = "/thank-you";
});

Web Form Custom Script (Server: Python)

In the Web Form document, add a Python script:

def get_context(context):
    # Add custom context variables for the template
    context.categories = frappe.get_all("Category", fields=["name", "title"])

Rule: NEVER trust client-side validation alone for Web Forms. ALWAYS validate in the target DocType's controller or server script.

Workflow 3: Enable has_web_view on a DocType

This makes individual documents accessible as web pages (e.g., /articles/my-article).

• Open DocType → check Has Web View and Allow Guest to View
• Set the Route field prefix (e.g., articles)
• ALWAYS add these fields to the DocType:
• route (Data, hidden) — auto-generated URL slug
• published (Check) — controls visibility
• Create templates in the DocType directory:
• {doctype_name}.html — single record template
• {doctype_name}_row.html — list item template
• In hooks.py, register as website generator:

website_generators = ["Article"]

• In the controller, implement get_context:

class Article(WebsiteGenerator):
    website = frappe._dict(
        template="templates/generators/article.html",
        condition_field="published",
        page_title_field="title",
    )

    def get_context(self, context):
        context.related = frappe.get_all(
            "Article",
            filters={"published": 1, "name": ("!=", self.name)},
            fields=["title", "route"],
            limit=5,
        )

Rule: ALWAYS include a published check field. NEVER expose unpublished documents to guests.

Workflow 4: Website Route Rules (hooks.py)

Route rules map URL patterns to controllers or pages.

# hooks.py
website_route_rules = [
    # Map parameterized URL to a page
    {"from_route": "/projects/<name>", "to_route": "projects/project"},
    # Map URL prefix to DocType
    {"from_route": "/kb/<path:name>", "to_route": "knowledge-base"},
]

# Redirects (301/304)
website_redirects = [
    {"source": "/old-page", "target": "/new-page"},
    {"source": r"/docs(/.*)?", "target": r"https://docs.example.com\1"},
]

# Homepage for logged-in users (role-based)
role_home_page = {
    "Customer": "orders",
    "Supplier": "rfqs",
}

# Dynamic homepage
get_website_user_home_page = "myapp.utils.get_home_page"

Priority order for homepage: get_website_user_home_page > role_home_page > Portal Settings > Website Settings.

Workflow 5: Blog Setup

• Create Blog Category documents (e.g., "News", "Updates")
• Create Blog Post documents:
• Select category, write content (Markdown or Rich Text)
• Set Published and Published On date
• Blog route auto-generates as /blog/{slug}
• Configure in Website Settings:
• Set blog title
• Enable/disable comments

Rule: ALWAYS set Published On date — posts without a date NEVER appear in RSS feeds.

Workflow 6: Website Theme & Custom CSS

Via Website Theme DocType

• Navigate to Website Theme → New
• Configure: fonts, colors, navbar style, button radius
• Add custom CSS in the Custom CSS field
• Set as active theme in Website Settings

Via hooks.py

# Inject CSS/JS on all web pages
website_context = {
    "favicon": "/assets/myapp/images/favicon.png",
}

update_website_context = "myapp.overrides.website_context"

# Override base template
base_template = "myapp/templates/custom_base.html"

Workflow 7: SEO: Meta Tags, Open Graph & Sitemap

In portal pages (frontmatter or context)

def get_context(context):
    context.metatags = {
        "title": "My Page Title",
        "description": "Page description for search engines",
        "image": "/assets/myapp/images/og-image.png",
        "og:type": "website",
        "twitter:card": "summary_large_image",
    }

In Web Page DocType

Set meta fields directly: Meta Title, Meta Description, Meta Image.

Sitemap

• Frappe auto-generates /sitemap.xml from published Web Pages and has_web_view documents
• Exclude pages: set sitemap = 0 in context or frontmatter
• Custom robots.txt: set robots_txt path in site_config.json

Rule: ALWAYS set meta description on public pages. NEVER leave it empty — search engines penalize pages without descriptions.

Workflow 8: Guest Access & Security

# site_config.json — rate limiting
{
    "rate_limit": {
        "web_form": "5/hour",
        "api": "100/hour"
    },
    "allowed_referrers": ["https://mysite.com"],
    "allow_cors": "https://mysite.com"
}

Security rules:

• ALWAYS enable CSRF protection (default). NEVER set ignore_csrf in production
• ALWAYS rate-limit guest-accessible endpoints
• ALWAYS sanitize user input in Web Forms (Frappe does this by default for standard fields)
• NEVER expose internal DocType names in guest-facing URLs without access control

Anti-Patterns

| Anti-Pattern | Correct Approach |

|---|---|

| Hard-coding HTML in get_context | Use Jinja templates with context variables |

| Skipping no_cache on dynamic pages | ALWAYS set no_cache = 1 for user-specific content |

| Guest Web Form without rate limiting | ALWAYS configure rate limits for guest forms |

| Missing published field on has_web_view | ALWAYS add published check to prevent data leaks |

| Using website_route_rules for simple redirects | Use website_redirects instead |

| Putting business logic in www/ controllers | Keep in DocType controllers; www/ is for presentation |
