Search form gives Component '' is not attached to ‘Nette\Application\UI\Presenter’

rolandd

Hello,

A newcomer to Nette here. I am trying to implement a search form, this form is used across multiple presenters but as the title says I get the error Component '' is not attached to 'Nette\Application\UI\Presenter'.

I have followed the following pages:

What I have eventually implemented is this.

app/forms/SearchFormFactory.php

<?php

namespace App\Forms;

use Nette\Application\UI\Form;


class SearchFormFactory
{
    public function create()
    {
        $form = new Form();
        $form->addText('search', 'Search');
        $form->addSubmit('send', 'Search');

        return $form;
    }
}

app/presenters/RulesPresenter.php

<?php

namespace App\Presenters;

use App\Forms\SearchFormFactory;
use App\Model\RuleManager;

class RulesPresenter extends BasePresenter
{
    private $ruleManager;

    public function __construct(RuleManager $ruleManager)
    {
        parent::__construct();

        $this->ruleManager = $ruleManager;
    }

    public function renderDefault()
    {

        $this->template->search = (new SearchFormFactory)->create();
        $this->template->rules  = $this->ruleManager->getRules();
    }
}

config.local.neon

services:
- App\Forms\SearchFormFactory

This generates the given error, when I remove the link to the SearchFormFactory, the page loads fine.

Where o where am I going wrong?

Thank you for any insights.

There is no createComponentSignInForm method, which creates the component.
Can you send how you use the component?

Also you should use dependency injection instead of manually creating SignInFormFactory.

<?php

namespace App\Presenters;

use App\Forms\SearchFormFactory;
use App\Model\RuleManager;

class RulesPresenter extends BasePresenter
{
    private $ruleManager;

	private $searchFormFactory;

    public function __construct(RuleManager $ruleManager, SearchFormFactory $searchFormFactory $searchFormFactory)
    {
        parent::__construct();

        $this->ruleManager = $ruleManager;
		$this->searchFormFactory = $searchFormFactory;
    }

    public function renderDefault()
    {
        $this->template->rules  = $this->ruleManager->getRules();
    }

	protected function createComponentSignInForm()
	{
		return $this->searchFormFactory->create();
	}
}

Hello @CZechBoY

Thank you for your quick reply and apologies for my late response. Life got in the way :)

So I have been following your pointers and here is what I have now. The searchFormFactory and translator are set in the parent. This gives me no error but I don't see the searchFormFactory form in the output either.

code

<?php

namespace App\Presenters;

use App\Forms\SearchFormFactory;
use App\Model\RuleManager;
use Kdyby\Translation\Translator;

class RulesPresenter extends BasePresenter
{
    private $ruleManager;

	/**
	 * Constructor.
	 *
	 * @param RuleManager       $ruleManager
	 * @param Translator        $translator
	 * @param SearchFormFactory $searchFormFactory
	 *
	 * @since     8.0.0
	 */
    public function __construct(RuleManager $ruleManager, Translator $translator, SearchFormFactory $searchFormFactory)
    {
        parent::__construct();

	    $this->ruleManager       = $ruleManager;
	    $this->translator        = $translator;
	    $this->searchFormFactory = $searchFormFactory;
    }

    /**
     * Render the page.
     *
     * @return  void
     *
     * @since   8.0.0
     */
    public function renderDefault()
    {
        //$this->template->search = (new SearchFormFactory)->create();
        $this->template->rules  = $this->ruleManager->getRules();
    }

	public function createComponentRulesForm()
	{
		return $this->searchFormFactory->create();
	}
}
?>

code

This is the neon file I am using.

{block content}

<table class="uk-table">
	<thead>
		<tr>
			<th>{_rules.name}</th>
			<th>{_rules.plugin}</th>
			<th>{_rules.action}</th>
		</tr>
	</thead>
	<tbody>
	<tr n:foreach="$rules as $rule">
		<td><a n:href="Rule:edit $rule->csvi_rule_id">{$rule->name}</a></td>
		<td>{$rule->plugin}</td>
		<td>{$rule->action}</td>
	</tr>
	</tbody>
</table>

You asked me to send you how I use this component. Not sure what you mean but here is what I plan to do. I want to show a list of rules and from this list the user can add or edit rules. Eventually these rules are used in the import and export of data. Before I get to those views, I must gather a lot more knowledge about Nette :)

Does this answer your question?

Component si rendered in latte using {control} macro. In your case in file templates/Rules/default.latte (or sth similar) you should add {control rulesForm} somewhere.

@CZechBoY Thank you so much for your patience with me. That was the missing link, adding the {control rulesForm} in my Presenter file made the search form show up. Now I can continue learning Nette. Have a great weekend.
