Question

编辑：细分

一天记录两次或更多次有日期实体和时间实体日期实体oneToMany：时间实体。
时间实体manyToOne：日期实体。

step1

表单字段由javascript添加。

step2

到目前为止，这么好。它确实可行。

问题是类别是随时间注册的。

step3

$form  = $this->createForm(new DateType(), new Date());

结构现在看起来像这样。

DateFormType collection with TimeFormType  
    TimeFormType collection with CategoryFormType  
    TimeFormType collection with SubCategoryFormType

Category Entity    oneToMany: Time Entity.  
SubCategory Entity oneToMany: Time Entity.  
Time Entity        manyToOne: Category Entity.  
Time Entity        manyToOne: SubCategory Entity.

如果出现这种情况，控制器会发生表单绑定错误。

$form->bind($request); // => Error: Category, array given 
Catchable Fatal Error: Argument 1 passed to ...\Entity\Time::setCategory() must be an instance of ...\Entity\Category, array given

通过“manyToOne”收集进行关系的“类别”吗？如何使用“表格集”错了？

详情如下。

我想实现日复一日的录音时间一天记录两次或更多次表单字段由javascript添加以下概述虽然很难解释它不会变长。

实体：

日期，类别，子类别，时间

Date.orm

Date:
    oneToMany:
        times:
            targetEntity: Time
            mappedBy: date
            cascade: ["persist", "remove"]

Time.orm

Time:
    // ...
    manyToOne:
        date:
            targetEntity: Date
            inversedBy: times
            joinColumn:
                name: date_id
                referencedColumnName: id
        category:
            targetEntity: Category
            inversedBy: times
            joinColumn:
                name: category_id
                referencedColumnName: id
        sub_category:
            targetEntity: SubCategory
            inversedBy: times
            joinColumn:
                name: sub_id
                referencedColumnName: id

Category.orm

Category:
    // ...
    oneToMany:
        times:
            targetEntity: Time
            mappedBy: categoy
            cascade: ["persist", "remove"]

    manyToMany:
        subs:
          targetEntity: SubCategory
          inversedBy: main
          joinTable:
            name: main_and_sub
            joinColumns:
                joinColum:
                    name: main_id
                    referencedColumnName: id
                    onDelete: CASCADE
            inverseJoinColumns:
                joinColum:
                    name: sub_id
                    referencedColumnName: id
                    onDelete: CASCADE

SubCategory.orm

SubCategory:
    // ...
    oneToMany:
        times:
            targetEntity: Time
            mappedBy: sub_category
            cascade: ["persist", "remove"]

    manyToMany:
        main:
            targetEntity: Category
            mappedBy: subs

TimeType

// ...
$builder->add('category', 'collection', array(
    'type' => new CategoryType(),
    'options' => array(
        'required'  => true,
    ),
    'allow_add'      => true,
    'by_reference'   => false,
    'allow_delete'   => true,
    'prototype'      => true,
    'prototype_name' => '__cat_prot__'
));
$builder->add('subcategory', 'collection', array(
    'type' => new SubCategoryType(),
    'options' => array(
        'required'  => false,
    ),
    'allow_add'      => true,
    'by_reference'   => false,
    'allow_delete'   => true,
    'prototype'      => true,
    'prototype_name' => '__cat_prot__'
));
$builder->add('time', 'time', array(
    'input'  => 'datetime',
    'widget' => 'choice',
));

DateType

// ...
$builder->add('date', 'date', array(
    'input'  => 'datetime',
    'widget' => 'choice',
));
$builder->add('times', 'collection', array(
    'type' => new TimeType(),
    'options' => array(
        'required'  => true,
    ),
    'allow_add'      => true,
    'by_reference'   => false,
    'allow_delete'   => true,
    'prototype'      => true,
    'prototype_name' => '__times_prot__'
));

查看：

{{ form_widget(form.date) }}

<ul id="TIMES" data-prototype="
    <div>
        {{ form_widget(form.times.vars.prototype.children['category'].vars.prototype.name) | e }}
        <label>Category 1</label>
    </div>
    <div>
        {{ form_widget(form.times.vars.prototype.children['subcategory'].vars.prototype.name) | e }}
        <label>Category 2</label>
    </div>
    <div>
        {{ form_widget(form.times.vars.prototype.time) | e }}
    </div>
    <input type='button' value='Remove' class='remove' />">
</ul>
<input type="button" value="add times" class="add-form-field" />

的javascript

var nums = 0;

$(document).on('click', '.add-form-field', function(e){
    var field  = $("#TIMES"),
        data   = field.attr("data-prototype"),
        widget = data.replace(/__cat_prot__/g, 0).replace(/__times_prot__/g, nums),
        newLi  = $('<li></li>').html(widget);
        newLi.appendTo("#TIMES");

    nums += 1;

    return false;
});

$(document).on('click', '#TIMES .remove', function(){
    $(this).parent().remove();
});

控制器：

$_date = new Date();
$form  = $this->createForm(new DateType(), $_date);

if ($request->getMethod() == 'POST') {
    $form->bind($request);  // => Error: Category, array given

$形式 - ＆GT;绑定（$请求）; // =＆gt;错误：类别，给定的数组

捕获致命错误：参数1传递给... \ Entity \ Time :: setCategory（）必须是... \ Entity \ Category的实例，给定数组

如果在这种情况下，“$ form-＆gt; bind（$ request）”有一个错误“Category，array given”。

是不是设计得很好？
最好不要使用表单构建器吗？

日期有时间时间有一个类别和一个子类别时间必须有一个类别时间没有子类别。（不是必须可以为空）

表单数据

date[date][day]

date[times][0][category][0][name]
date[times][0][subcategory][0][name]
date[times][0][time][hour]
date[times][0][time][minute]

date[times][1][category][0][name]
date[times][1][subcategory][0][name]
date[times][1][time][hour]
date[times][1][time][minute]

~~我认为“date [times] [0] [category] [0] [name]”必须是“date [times] [0] [category] [name]”。~~
我认为整合表格的方式是错误的。

Symfony2：是否有可能从“manyToOne”的“多”侧实体收集表格？
