Re: [Pharo-users] Mustache: Making a conditional section show its values.

May 29, 2017

      Yes I can share the data. Please load Brea project from [1] and do:

=========

| testUser  |
testUser := BreaMember new createTestUser.
testUser html

=========

[1] http://smalltalkhub.com/#!/~Offray/Brea

You will see that the twitter portion of the row is showed, but without
any actual data inside. You can also try this:

=========
'{{#twitter}}
             <tr>
               <td
class="mdl-data-table__cell--non-numeric"><b>Twitter</b></td>  
               <td class="mdl-data-table__cell--non-numeric">
                 <a
href="https://twitter.com/{{twitter}}">{{twitter}}</a></td>
             </tr>
{{/twitter}}' asMustacheTemplate value: { #twitter -> '@offrayLC'   }
asDictionary
=========

with the same behavior.

I think that the proper output will be the row showed with the data
inside filled.

Let me know how can I help to debug this.

Thanks,

To clarify. If the object you inject has a value which either does not contain the key twitter or it does container the key twitter but its value is nil then the section won't be shown.
'{{#twitter}}
             <tr>
               <td
class="mdl-data-table__cell--non-numeric"><b>Twitter</b></td>   
               <td class="mdl-data-table__cell--non-numeric">
                 <a
href="https://twitter.com/{{twitter}}">{{twitter}}</a></td>
             </tr>
{{/twitter}}' asMustacheTemplate value: { #twitter -> nil   } asDictionary
gives empty string in my case.

Can you show some data you are injecting? It should work as you expect it.

Hi,
I'm using Mustache for a project to build a dynamic distributed web site
generator for public & open data, backed by Fossil and using Material
Design Lite. I have a template like this:
========
{{#twitter}}
            <tr>
              <td
class="mdl-data-table__cell--non-numeric"><b>Twitter</b></td>   
              <td class="mdl-data-table__cell--non-numeric">
                <a
href="https://twitter.com/{{twitter}}">{{twitter}}</a></td>
            </tr>
{{/twitter}}
========
that is mean to show or hide a row in a table, depending on if Twitter
data for a profile is found in a user profile. When the profile doesn't
have twitter data, the row is hidden, as supposed, and when it has, the
row is shown, but without any actual twitter data. What I'm missing?
Should I use partials in this case and how?
Thanks,
