I've started localizing my Symfony project but when I tried to use the __() function inside actions.class.php it came up with an error: Call to undefined function __(). The texts I have inside actions class are the form's labels and errors.
How can I localize these labels and errors if I am not allowed to use __() function? Is the simple translation into the catalogue enough? The same question applies for the Form classes.
Thank you.
in form $this->widgetSchema->setLabel('foobar'); will be automaticly translated: http://www.symfony-project.org/forms/1_4/en/08-Internationalisation-and-Localisation
the __() function usually works only in the templates with enabled i18n helper.
if you want to translate something in the action you will have to load the helper there. sfLoader::loadHelpers(array('I18n'));

I have some html that is used a lot in the site i'm building. So I created a App_Code\Helpers.cshtml file and placed the helperfunction in that file.
Now, I want to render a partial-view (a MVC view for a form). But I can't use #Html.Partial("MyFormPartial", new formModel())
I can't find any other ways of rendering a partial view from within a helper class. Anybody got an idea on how to solve this?
Is a seperate helpers.cshtml even the best way for this kind of repeating html-code? I think it gives me a bit more freedom in the parameters I'm providing, instead of the macro's. But it sucks I can't use #Umbraco (without creating your own helper) or #Html :(
Just pass #Html to the helper function if you don't want to create it inside the helper function.
Nevertheless, isn't it a better idea to use a child action and render part of code you'd like to been shared?
The problem I have faced is I want to create an HTML helper method to create a specific element which uses some JavaScript code to work fine. But, I want to add script tag automatically to the HTML, if the helper is used in the view.
If the helper is called more than once in the view, it is undesirable to add more than one script tag.
Now, Is it possible and if so How can I do that?
Thanks for your answers.
I have a form_for in all of my views. Now I need to insert a hidden html input element in all of these views.
Is there anyway I could specify a wrapper over form using partials where I take all the form parameters , do my own logic of inserting the hidden input element and render the rest of the block given by the views? How can I do this?
Yes, I think you can write your own logic in views through helpers, Helpers provide you more flexibility, consistency, and also provide functionality to keep your code DRY(the basic feature of Rails). you can write your helper methods in app/helpers/application_helper.rb.
You can have a look on this guide:
http://guides.rubyonrails.org/form_helpers.html
Hope it will help you in what you were looking for.Thanks
Hi I'm working with a project (asp.net mvc) where I need to show pictures on one site. They gone have jquery and be surrounded by a div like <div><img/></div>
I'm relatively new on MVC so I'm not sure what ways are the best to work in it yet. Should I do a ImageHelper so i can access it like <% Html.ImageJquery() %> or should i just do it plain in the view
what are your thoughts on this?
I am not sure if there is any single best practice for this case. As you already said you could create an extension method on a HtmlHelper or just put the code in the view.
Because the "added" code is a very simple (just two divs) I would skip extension method and just add the divs in the view. But if the code is actually more complex I would create a helper.
Cheers!
It depends how often you would use the helper. If it is used in a couple of places it would make sense, because it helps you to reduce redundant code.
The other option you have are partials.
I would go with an Extension method on the HTMLHelper , so that it accepts the 'src' value as a parameter and constructs the image tag accordingly.
Regarding Rendering of UI elements , i did read a blog post on 'Conditional Rendering' which i thought you would find it interesting .

I have a submit button that is a block of HTML code because of styling and images to make it look better. (I stole most of it from Wufoo).
This is one every form in the application and I was wondering if there is a cleaner way to do this. Something like a partial or helper?
The name of the button "Submit" or "Add Contact" needs to be a variable.
snippet
Add Contact #variable text
Back

You can use a application-wide helper for this. Helpers are modules containing methods that are shared by multiple views. You can easily define your own helper that works like the 'submit_tag' helper method that generates the button.
consider partials (http://api.rubyonrails.org/classes/ActionView/Partials.html)
Seems like something partials were invented for.
