python - jinja2蓝图路线错误

Question

我正在开发一个 Python-Flask 应用程序，并尝试实现一个简单的搜索功能:

home/views.py

from . import home_blueprint
################################# SEARCH #################################


@home_blueprint.route("/search")
@login_required
def search():
    results = Politic.query.whoosh_search(request.args.get('query')).all()
    #results = Politic.query.whoosh_search(query).all()
    for p in results:
        print p.publicName
    print results
    return render_template('search_results.html',
                           results=results)

非常简单，在我将蓝图纳入我的项目之前，我就让它工作了。当我在我的 View 中调用这个函数时，我什么也得不到。

已更新!我的base.html文件:

<form class="form-inline" method="GET" action="{{url_for('home.search')}}">
              <div class="form-group">
                  <label for="query">Poltician</label>
                  <input type="text" class="form-control" name="query" id="query">
              </div>
              <button type="submit" class="btn btn-primary">Search</button>
          </form>

由于 url_for 查找函数，因此我传递了 home_blueprint 和我想要调用的函数(搜索)。

有什么原因导致我无法进入搜索功能吗？我在 .html 文件中做错了什么吗？

致以诚挚的问候

编辑:(init.py)

@app.before_request
def before_request():
    g.user = current_user
    if g.user.is_authenticated:
        g.user.last_seen = datetime.datetime.utcnow()
        db.session.add(g.user)
        db.session.commit()
        g.search_form = SearchForm()


@login_manager.user_loader
def user_loader(email):
    """Given *user_id*, return the associated User object.

    :param unicode user_id: user_id (email) user to retrieve
    """
    return User.query.filter_by(email=email).first()

编辑我的项目树:

我做了metmirr建议的更改，现在我的项目结构是这样的:project/home/__init__.py

from flask import Blueprint

home_blueprint = Blueprint(
    'home', __name__,
    template_folder='templates'
)

from . import views

URL 当我搜索时:

http://localhost:5000/home?query=new

何时应该:

http://localhost:5000/search?query=new

不过，它并没有进入搜索功能。我不知道我做错了什么。

任何帮助都很棒!谢谢。

如果您在项目中打开 python 解释器(如果您使用的是虚拟环境，请确保激活虚拟环境)，您可以检查应用程序上注册的端点以及它们指向的函数。

>>> import app
>>> app = app.create_app()
>>> app.url_map
Map([<Rule '/search' (OPTIONS, POST) -> **folder_where_your_search_views_are_located**.search>,
     <Rule '/search_results/<query>' (OPTIONS, GET) -> **folder_where_your_search_views_are_located**.search_results>])
