How to generate JSON-LD in Flask

from flask import render_template, url_for

@app.get("/guide")
def guide():
    schema = {
        "@context": "https://schema.org",
        "@type": "TechArticle",
        "@id": url_for("guide", _external=True) + "#article",
        "headline": "Example Technical Guide",
        "mainEntityOfPage": url_for("guide", _external=True),
    }
    return render_template("guide.html", schema=schema)

{% if schema %}
<script type="application/ld+json">{{ schema|tojson }}</script>
{% endif %}

• Use the JSON serializer rather than marking hand-built strings safe.
• Generate absolute canonical URLs.
• Do not expose private model fields.
• Keep data synchronized with the visible page.

• Define the purpose and expected result of generate json-ld in flask.
• Capture the current state using visible entities, page purpose, JSON-LD graphs, identifiers, relationships, required properties, and consumer-specific eligibility.
• Identify the source template, component, plugin, content owner, and release path that controls the output.
• Prepare a test case, approval path, backup or rollback method, and post-release verification plan.

• Parse the deployed json-ld, validate the graph, compare it with visible content, and test any target consumer requirements.
• Check representative page types and edge cases instead of confirming only the example used during implementation.
• Confirm the change did not create publishing properties that are unsupported, hidden, stale, or inconsistent with visible content.
• Record the implementation date, owner, release reference, evidence, and next review trigger.
