I can't figure why my block is not displayed as expected. Here what i've done to debug this. First of all my layout:

<layout>
<vendor_contest_contest_index translate="label" module="vendor_contest">
    <label>Contests list</label>
    <update handle="page_one_column" />
    <reference name="content">
        <block type="vendor_contest/contest_list" name="contest_list" template="vendor_contest/contest/list.phtml" />
    </reference>
</vendor_contest_contest_index>
<vendor_contest_contest_view translate="label" module="vendor_contest">
    <label>Contest view page</label>
    <update handle="page_one_column" />
    <reference name="content">
        <block type="vendor_contest/contest_view" name="contest_view" template="vendor_contest/contest/view.phtml" >
            <block type="vendor_contest/contest_content" name="contest_content" template="vendor_contest/contest/content.phtml" />
            <block type="vendor_contest/contest_answer_list" name="contest.answer_list" as="contest_answers" template="vendor_contest/contest/answer/list.phtml" />
            <block type="vendor_contest/contest_answer_answered" name="contest.answer_answered" as="contest_answered" template="vendor_contest/contest/answer/answered.phtml" />
        </block>
    </reference>
</vendor_contest_contest_view>
</layout>

Here is the contest_view block :

public function getAnswersListView()
{
    return $this->getChildHtml('contest.answer_list');
}

public function getAlreadyAnsweredView()
{
    return $this->getChildHtml('contest.answer_answered');
}

public function hasCustomerAnswered()
{
    $answered = false;
    $contest = $this->getCurrentContest();
    $customer = Mage::getSingleton('customer/session')->getCustomer();
    $collection = Mage::getModel('vendor_contest/participation')->getCollection();
    $collection
            ->addFieldToFilter('customer_id', $customer->getId())
            ->addFieldToFilter('contest_id', $contest->getId())
            ->load();
    if (count($collection)) {
        $answered = true;
    }
    return $answered;
}

And my view.phtml

echo $this->getChildHtml('contest_content');
if ($this->hasCustomerAnswered()) {
     echo $this->getAlreadyAnsweredView();
} else {
    echo $this->getAnswersListView();
}

Here only the block contest_content is diplsayed. If i change the first line to

echo $this->getChildHtml();

All my blocks are displayed. That means there is no error in my block code, i guess. Both my system.log and error.log are empty.

If needed i can provide more files. Just tell me which one you'd like to see.

On my side i tried to debug this way : i went to 

app/code/core/Mage/Core/Block/Abstract.php

and i dumped $childName in it.

string(15) "contest_content" string(19) "contest.answer_list" string(23) "contest.answer_answered"

And my three blocks are effectively displayed below.

I didnt manage to understand deeper why my block aren't displayed with the above snippets of code.

Thanks you all who'll take time to read this.

EDIT : here's my Content.php

<?php

class Vendor_Contest_Block_Contest_Content extends Vendor_Contest_Block_Contest_View
{

}

Notice the extends. Since basically block Content doesnt need anything more than View it felt right to me to extends Contest_View.

  • Could you post the content of your vendor_contest/contest_content block please ?

  • What happens if you make this block extend Mage_Core_Block_Template instead ?

    No it didnt. I'll try to be more clear. As you can see in my layout i have 3 blocks depending of contest_view. When i call echo $this->getChildHtml('contest_content'); from my view.phtml the block is rendered. BUT when i do echo $this->getAnswersListView(); or echo $this->getAlreadyAnsweredView(); those blocks ARE NOT rendered. But a call to getChildHtml(); render them all. Does it make more sense to you ?

    Yes, clearer. Change your block name from contest.answer_list to answer_list in both your layout and your block function. Do the same for the contest.answer_answered block. I reckon the name does not match Magento standards.

Thank to the help provided by @Digital Pianism in the comments I noticed getChildHtml() expects to be given an ALIAS block and not its name (if it exists). Don't be fooled by the variable name $childName in the core if you have to go through it.
