在jinja2模板中创建Flask应用程序的链接

问题描述

 像 url_for 这个功能用于创建Flask这样的URL：
 
 
  url_for（'view_name'，** arguments）
  
 
 $ b $我已经尝试过寻找一个，但我，我不能找到它。
解决方案
在这里问两个问题，但我会拍一些... 
 
 
 
对于发布网址，您可以这样做：
 < a href ={{url_for（'post_blueprint.get_post'，year = year，month = month，title = title）}}> 
 {{title}} 
< / a> 
  
为了处理静态文件，我强烈建议使用像，但要用香草瓶来做：
  {{url_for（'static'，filename ='[filenameofstaticfile]'）}} 
  
如果您想了解更多信息，我强烈建议您阅读。 和 
 
 
 
 使用kwargs编辑：
 
 
 如果你想使用 url_for  
 $ b 
  {{url_for（'post_blueprint.get_post'，** post）}} 
  code> 
您必须将您的视图更改为如下所示：
 
 
 <$ p $ 
 def get_all_posts（）：
 models = database_call_of_some_kind＃这是假设你使用某种模型
的职位
 posts.append（dict（year = model.year，month = model.month，title = model.title））
 return render_template（'p热媒那么你的模板代码可能看起来像这样：$ / $ p 
 
 
 
 
 
 
 
 
 
  {在帖子中发帖％} 
  {{post ['title']}} 
< / a> 
 {％endfor％} 
  
此时我会在模型上创建一个方法所以你不必把它变成一个字典，但这么做取决于你： - ）。
 
In my Flask app, I have a view which displays a post
@post_blueprint.route('/post/<int:year>/<int:month>/<title>')
def get_post(year,month,title):
    # My code
To display the last 10 entries, I have following view:
@post_blueprint.route('/posts/')
def get_all_posts():
    # My code
    return render_template('p.html',posts=posts)
Now when I display the last 10 posts, I want to convert the title of a post into a hyperlink.Currently I have to do the following in my jinja template to achieve this:
<a href="/post/{{year}}/{{month}}/{{title}}">{{title}}</a>
Is there any way to avoid hard coding the url? 
Like url_for function which is used to create Flask urls like this:
url_for('view_name',**arguments)
I have tried searching for one but I,m not able to find it.
 解决方案 
I feel like you're asking two questions here but I'll take a shot...
For the posting url you'd do this:
<a href="{{ url_for('post_blueprint.get_post', year=year, month=month, title=title)}}">
    {{ title }}
</a>
To handle static files I'd highly suggest using an asset manager like Flask-Assets, but to do it with vanilla flask you do:
{{ url_for('static', filename='[filenameofstaticfile]') }}
If you'd like more information I highly suggest you read. http://flask.pocoo.org/docs/quickstart/#static-files and http://flask.pocoo.org/docs/quickstart/#url-building
Edit for using kwargs:
Just thought I'd be more thorough...
If you'd like to use url_for like this:
{{ url_for('post_blueprint.get_post', **post) }}
You have to change your view to something like this:
@post_blueprint.route('/posts/')
def get_all_posts():
    models = database_call_of_some_kind # This is assuming you use some kind of model
    posts = []
    for model in models:
        posts.append(dict(year=model.year, month=model.month, title=model.title))
    return render_template('p.html', posts=posts)
Then your template code can look like this:
{% for post in posts %}
    <a href="{{ url_for('post_blueprint.get_post', **post) }}">
        {{ post['title'] }}
    </a>
{% endfor %}
At this point I would actually create a method on the model so you don't have to turn it into a dict, but going that far is up to you :-).
