I want to print the docstring of a python function from inside the function itself.
for eg.

    def my_function(self):
      &quot;&quot;&quot;Doc string for my function.&quot;&quot;&quot;
      # print the Docstring here.

At the moment I am doing this directly after `my_function` has been defined.

    print my_function.__doc__

But would rather let the function do this itself.

I have tried calling `print self.__doc__` `print self.my_function.__doc__` and `print this.__doc__` inside my_function but this did not work.

How to print Docstring of python function from inside the function itself?

I had the code:

    std::string st = &quot;SomeText&quot;;
    ...
    std::cout &lt;&lt; st;

and that worked fine. But now my team wants to move to `wstring`.
So I tried:

    std::wstring st = &quot;SomeText&quot;;
    ...
    std::cout &lt;&lt; st;

but this gave me a compilation error:

&gt; Error	1	error C2664:
&gt; &#39;std::basic_string&lt;_Elem,_Traits,_Ax&gt;::basic_string(const
&gt; std::basic_string&lt;_Elem,_Traits,_Ax&gt; &amp;)&#39; : cannot convert parameter 1
&gt; from &#39;const char [8]&#39; to &#39;const std::basic_string&lt;_Elem,_Traits,_Ax&gt;
&gt; &amp;&#39;	D:\...\TestModule1.cpp	28	1	TestModule1

After searching the web I read that I should define it as:

    std::wstring st = L&quot;SomeText&quot;; // Notice the &quot;L&quot;
    ...
    std::cout &lt;&lt; st;

this compiled but prints `&quot;0000000000012342&quot;` instead of `&quot;SomeText&quot;`.

What am I doing wrong ?

I need to generate some JSON content in controller and I need to get the full URL to an uploaded image situated here : `/web/uploads/myimage.jpg`.

I only want to have email as mode of login, I don&#39;t want to have username. Is it possible with symfony2/symfony3 and FOSUserbundle?

I read here http://groups.google.com/group/symfony2/browse_thread/thread/92ac92eb18b423fe

But then I am stuck with two constraint violations.

Problem is if the user leaves the email address blank, I get two constraint
violations:

 * Please enter a username
 * Please enter an email

Is there a way to disable validation for a given field, or a better way to
remove a field from the form altogether?

In Twig template I check if a field has an error like this:

    {% if form.points.get(&#39;errors&#39;) is not empty %}

Is there any method like:

    {% if form.points.hasErrors() %}

to do it simpler? It&#39;s not a big difference, but if I can&#39;t do it easier why not.



Simple check if form field has errors in Twig template

I am using a login form on Symfony2 with the following controller code

    public function loginAction(Request $request)
    {
        $user = new SiteUser();
        $form = $this-&gt;createForm(new LoginType(), $user);
        
        
        if ($request-&gt;getMethod() == &#39;POST&#39;) {
            $form-&gt;bindRequest($request);
            $data = $form-&gt;getValues();
            // Need to do something with the data here
        }
        
        return $this-&gt;render(&#39;GDSiteBundle::header.html.twig&#39;, array(&#39;form&#39; =&gt; $form-&gt;createView()));
    }

But I am getting the following warning:

&gt; Warning: array_replace_recursive() [&lt;a href=&#39;function.array-replace-recursive&#39;&gt;function.array-replace-recursive&lt;/a&gt;]: Argument #1 is not an array in &lt;PATH&gt;\vendor\symfony\src\Symfony\Component\Form\Form.php line 593
500 Internal Server Error - ErrorException

Can someone help me understand whats incorrect, and how I can fix it? Thanks.

Update:
The twig file is something like this:

    &lt;div class=&quot;form&quot;&gt;
        {{ form_errors(form) }}
        &lt;form action=&quot;{{ path(&#39;site_user_login&#39;) }}&quot; method=&quot;POST&quot; {{ form_enctype(form) }}&gt;
            &lt;div class=&quot;level1&quot;&gt;
                {{ form_row(form.username) }}
                &lt;a href=&quot;javascript:void(0)&quot; id=&quot;inscription&quot;&gt;{% trans %}Registration{% endtrans %}&lt;/a&gt;
            &lt;/div&gt;
            &lt;div class=&quot;level2&quot;&gt;
                {{ form_row(form.pwd_hash) }}
                &lt;div class=&quot;forget_pass&quot;&gt;&lt;a href=&quot;#&quot; id=&quot;frgt&quot;&gt;{% trans %}Forgot Password ?{% endtrans %}&lt;/a&gt;&lt;/div&gt;
            &lt;/div&gt;
            &lt;input type=&quot;submit&quot; class=&quot;submit&quot; name=&quot;login&quot; value/&gt;
            &lt;div class=&quot;clr&quot;&gt;&lt;/div&gt;
        &lt;/form&gt;
    &lt;/div&gt;

Here is the function in the Form&#39;s Type

    public function buildForm(FormBuilder $builder, array $options)
    {
        $builder-&gt;add(&#39;username&#39;, &#39;text&#39;, array(&#39;label&#39; =&gt; &#39;Username : &#39;));
        $builder-&gt;add(&#39;pwd_hash&#39;,&#39;password&#39;, array(&#39;label&#39; =&gt; &#39;Password : &#39;));
    }

Here is the route:

    site_user_login:
        pattern: /{_locale}/login
        defaults: {_controller: GDSiteBundle:SiteUser:login}

I looked around for the code to get the current path in a Twig template (and not the full URL), i.e.
I don&#39;t want `http://www.sitename.com/page`, I only need `/page`.

How can I set member of an already existing array from Twig?

I tried doing it next way:

    {% set arr[&#39;element&#39;] = &#39;value&#39; %}

but I got the following error:

How can I render a block multiple times within a view in a twig template? Currently I do have a block, let&#39;s call it `something` defined in an included (via `render `) twig file. I then include it at the layout-twig file using the following:

    {% block something %}{% endblock %}

Everything is fine, however as soon as I call this tag a second time, I get the following error message:

    The block &#39;something &#39; has already been defined in &quot;::layout.html.twig&quot; 

Therefore: How can I render a block multiple times?

How can I reuse a block multiple times?

In Symfony 2 templates (using Twig), how can I effectively check whether a user is not logged in?

I don&#39;t want to use `ROLE` checks. I want a straightforward way to check if a user is not logged in.

I&#39;m aware that comparing `app.user.username` with `anon` works, but that just doesn&#39;t feel right to me.
