In a Symfony form, how could I add some dummy errors to test how errors are printed ?
I would like to test all errors : global ({{ form_errors(form) }}) and widget-specific ({{ form_row(form.tags) }})
I've searched throught all these documentation links and didn't find anything.
I also looked about validators but nothing seems to match.
here you are (in your controller):
use Symfony\Component\Form\FormError;
$form->get('yourAttribute')->addError( new FormError('your error message'));

I am developing a Shopify Theme. The structure I have now is (excerpt):
Snippets
custom-message-snippet
Sections
custom-message-section
welcome-page-a-section
welcome-page-b-section
Templates
welcome-page-a-template
welcome-page-b-template
...
Custom message snippet uses settings that are in the custom-message-section, that is:
a) message
b) header text
I'd like for users to be able to add custom-message-snippet to welcome-page-a and welcome-page-b in a way that settings for both are different.
I can not render section 'custom-message-section" inside welcome pages because it is not possible (and a workaround is nasty).
There are fifty welcome pages. Every welcome page is totally different.
My question is:
How to allow users to use custom-message-snippet in all welcome pages without copying and pasting custom-message-page setting schema to each and every welcome page?
combine custom-message-section to custom-message-snippet
combine welcome-page-\w+-template to welcome-page-template, you only need to have one template and schema set, the user will control the sections in schema selection.
in template, use schema to select the page-content; this, defined by a bunch of if-else /switch statement.
{% section "welcome-page-custom-message-section" %}
{% section "welcome-page-content" %}
in welcome-page-custom-message-section
{% render "custom-message-snippet" with "string from welcome-page-section schema " %}
create checkbox select schema for custom message to appear or not.
Short: You can't.
Long: Using storefront 2.0, you end you having blocks, which can be added manually to any template.
It is possible if you have a little knowledge of Node.js and you're using the Shopify CLI.

I just started running my blog using Github pages.
I chose 'minimal mistakes' theme and encountered a problem while customizing.
{% assign posts = site.categories.['Effective Java'] %}
The reason why I used square bracket is because of the blank between 'Effective' and 'Java'.
It actually works well without any problems, but I don't want to see the Liquid Warning any more.
Is there a better way to deal with the blank?
I can't figure out how to get variables into Sphinx documents via a template. I am certainly making an elementary mistake, but while there is lots of documentation for using Jinja/Flask templates for web service and some documentation for Sphinx using it, I am having trouble doing the following. Maybe it's not possible and I'm barking up the wrong tree, but then this is fairly different from how variables work in general in web (as opposed to doc) templates?
I am working within a much larger project. Suppose in my project's conf.py I make a variable, say
LANGS = ['en', 'de', 'cn']
I know that this works because if I do the docbuild (we have a custom docbuild but I don't think it does anything really crazy other than a customized logger and eating a bunch of 'chatter') with the following line in conf.py
print len(LANGS)
it shows up during the docbuild.
But now of course I want to access this variable in my template. As far as I can tell, we override index.rst with templates/index.html, which inherits from the basic layout.html for Sphinx. And if I do
<p>We have {{ LANGS|len }} languages</p>
I get
We have 0 languages
Now, this is weird, because sometimes I can cause an error in the build by referring to variables not defined (though not consistently), so that somehow it 'knows' that the variable is defined but thinks it has length zero. Or does a "null" variable have length zero automatically?
How do I get this variable defined - or is it not possible?
What I want to do is then do something for each language in the list (make an outside link, in particular), but I figure there is no point in trying {% for %}/{% endfor %} or whatever if I can't get this working. Maybe Sphinx implements only a subset of Jinja?
Anyway, please help!
There are at least two ways to pass variables to a template:
Via html_context:
A dictionary of values to pass into the template engine’s context for all pages. Single values can also be put in this dictionary using the -A command-line option of sphinx-build.
Example:
# conf.py:
html_context = {'num_langs': len(LANGS)}
<!-- template: -->
<p>We have {{ num_langs }} languages</p>
Via the html_theme_options. This requires adding an option to theme.conf (you can create a theme by inheriting from a standard one):
[options]
num_langs = 1
Then you can set num_langs in conf.py via html_theme_options:
html_theme_options = {'num_langs': len(LANGS)}
and use it in a template:
<p>We have {{ theme_num_langs }} languages</p>
Test.vbhtml
<span>The time is #DateTime.Now.</span>
#Helper Time()
#<p>The time is #DateTime.Now.</p>
End Helper
Note the full stop (.) at the end of the #DateTime.Now
MVC3 accepts Test.vbhtml. Both the <span> line and the #Helper compile.
MVC4 gets a compilation error in the helper only:
Compiler Error Message: BC30203: Identifier expected.
The <span> in MVC4 works but the #Helper does not.
A solution is easy enough, such as replacing the full stop with .. But why does this happen?
Edited for clarification.
With the dot placed as such the compiler looks for a property or method name. Do like this instead:
#<p>The time is #(DateTime.Now).</p>
If you really want to use # sign then use as shown below. it solves the problem.
razor tries to look for #sign before rendering so it creates problem.
<text>#</text><p>

The way I get it to show up on the index page is adding this code to the core index.php page right below this:
// Assign index specific vars
'S_AVATAR' => get_user_avatar(
$user->data['user_avatar'],
$user->data['user_avatar_type'],
$user->data['user_avatar_width'],
$user->data['user_avatar_height']
),
Then I can use {S_AVATAR} in my template but it ONLY shows up in the index file... So another phpbb guy suggested that I take that same code from above and place it in the includes/functions.php file right below this:
// The following assigns all _common_ variables that may be used at any point in a template.
I did that, and though it seemed to "try" and work I clicked on a few pages outside the index page and got a fatal error message:
Fatal error: Call to undefined function get_user_avatar() in /home/content/04/6534704/html/phone7forum/includes/functions.php on line 4385
Does anyone have any ideas?
IIRC get_user_avatar() is a function from functions_display. If you want to use it in the functions file, you have to include it.
Put it into an if condition to have it only load if you're on a page where function_display isn't already included:
if(!function_exists('get_user_avatar')){ include_once($phpbb_root_path . 'includes/functions_display.' . $phpEx); }
