Ich erhalte die folgende Fehlermeldung beim Versuch {% set foo = 42 %} in meiner HTML-Vorlage. Die Vorlage funktioniert einwandfrei, wenn set nicht verwendet wird.Jinja2 installieren Problem

TemplateSyntaxError: Invalid block tag: 'set', expected 'endblock' or 'endblock content'

Unten habe ich das vollständige Sitzungsprotokoll wie in den Kommentaren vorgeschlagen hinzugefügt.

Unten habe ich die Revisionen hinzugefügt ich meine views.py gemacht. Die auskommentierten Zeilen geben die ursprünglichen jinja2-Umgebungsbedingungen an. Diese Überarbeitungen sind auf Vorschläge in Kommentaren zurückzuführen. Aber ich bekomme immer noch die gleiche Fehlermeldung, die darauf hindeutet, dass jinja2 nicht benutzt wird.

TEMPLATE_DIR = os.path.join(os.path.dirname(__file__), 'templates') 
#jinja_environment = \ 
#jinja2.Environment(loader=jinja2.FileSystemLoader(TEMPLATE_DIR)) 

JINJA_ENVIRONMENT = jinja2.Environment(
    loader=jinja2.FileSystemLoader(os.path.dirname(__file__)), 
    extensions=['jinja2.ext.autoescape'], 
    autoescape=True) 

class BaseHandler(webapp2.RequestHandler): 

    @webapp2.cached_property 
    def jinja2(self): 
     return jinja2.get_jinja2(app=self.app) 

    def render_template(
     self, 
     filename, 
     template_values, 
     **template_args 
     ): 
#template = jinja_environment.get_template(filename) 
    template = JINJA_ENVIRONMENT.get_template(filename) 
     self.response.out.write(template.render(template_values))

Unten ist die Vorlage base.html.

<html> 
    <head> 
    <link rel="stylesheet" href="/static/css/reset.css"> 
    <link rel="stylesheet" href="/static/css/style.css"> 
    </head> 
    <body> 
    <div class="wrapper"> 
    {% block content %} 
    {% endblock content %} 
    </div> 
    </body> 
</html>

Unten ist das "Herz" der tatsächlichen Vorlage. Mit "Herz", ich meine, ich habe die Eingeweide weggelassen, weil dies nur ein Test ist.

{% extends "base.html" %} 
    {% block content %} 
    <center> 
     <h1>Create or edit your own Blog</h1> 
     </center> 
     {% set foo = 42 %} 
     {{ foo }} 

    {% endblock content %}

This answer suggests to me that jinja2 is not installed (properly?).

Gibt es einen anderen Teil der Installation, die ich ändern müssen?

This answer shows more input about ipython installation, aber ich verwende google-app-engine, die unterschiedlich sein können. Die folgende Liste bestätigt, dass Jinja2 2.8 installiert ist.

Dürfen wir Ihre Vorlage oder zumindest den vollständigen Block Ihrer verdächtigen Aussage sehen? –

Ja, bitte schauen Sie sich die überarbeitete Frage an. – zerowords

Syntax ist korrekt für Jinja2.Aber Ihre App scheint Django-Vorlagen zu verwenden, keine Jinja2-Einsen - Syntax ist etwas anders. Siehe @ Blenders Kommentare zu http://stackoverflow.com/questions/20306640/is-jinja2-documentation-out-of-date. –

Nach viel Hilfe über Kommentare zu meiner ursprünglichen Frage und zu viel Stolpern, habe ich endlich meine Frage beantwortet. Ich war verwirrt von Webapp2 und Jinja mit einem template.render(), aber sie sind anders.

template.render() von webapp scheint 2 Parameter zu erfordern - der Pfad und der Vorlagenname - und mein aktueller Code verwendet dieses Format. Ich möchte jedoch Jinja2 verwenden, wo template.render() nur 1 Parameter benötigt - den Vorlagennamen.

Entsprechend der google docs for using Jinja in the guestbook app wurde das folgende Format angezeigt.

JINJA_ENVIRONMENT = jinja2.Environment(
    loader=jinja2.FileSystemLoader(os.path.dirname(__file__)), 
    extensions=['jinja2.ext.autoescape'], 
    autoescape=True)

Aber es stellt sich heraus, dass nicht gut mit meinem gewählten BaseHandler Klasse funktioniert, die Vorlagen in ihrem eigenen Unterverzeichnis ausdrückt, „Vorlagen“. Stattdessen habe ich den folgenden Code verwendet, bei dem TEMPLATE_DIR Datei im "loader =" - Satz ersetzt.

TEMPLATE_DIR = os.path.join(os.path.dirname(__file__), 'templates') 
JINJA_ENVIRONMENT = jinja2.Environment(
    loader=jinja2.FileSystemLoader(TEMPLATE_DIR), 
    extensions=['jinja2.ext.autoescape'], 
    autoescape=True)

Btw, ich importieren nicht mehr die Webapp template. Und ich benutze den folgenden Stil in meinen "get def" s.

template = JINJA_ENVIRONMENT.get_template('index.html') 
self.response.out.write(template.render(template_values))

Also, auch wenn die Frage stellt „Jinja installiert Problem“, ist es nicht genau das war die Installation, das war problematisch, vielmehr hatte ich Schwierigkeiten Jinja mit meiner vorhandenen Verzeichnisstruktur zu integrieren.
