I have not found any easy way to accomplish to simply check a Checkbox by default. That can not be that hard, so what am i missing?

推荐答案

您只需将模型或实体中的值设置为true，然后将其传递给FormBuilder，则应进行检查。

You would simply set the value in your model or entity to true and than pass it to the FormBuilder then it should be checked.

如果您看一下文档：

创建新任务，然后执行setTask并添加此任务到FormBuilder。如果您对复选框执行相同的操作

A new task is created, then setTask is executed and this task is added to the FormBuilder. If you do the same thing with your checkbox

$object->setCheckboxValue(true);

并传递对象，您应该会看到该复选框处于选中状态。

and pass the object you should see the checkbox checked.

如果它没有按预期工作，请返回一些示例代码以重现该错误。
