问题 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? 回答1: 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.

问题 I have a Controller where I'm creating a list of open Jobs and populate them in a table via Twig. What I want now is that the last field of each line is an upload form, so that you can add files to one specific job.

I already have the code that displays the radio button list but want to DRY it up by refactoring into a formbuilder. I can't find any examples of a custom form builder for radio button lists. Any pointers/links would be appreciated. 回答1: Assuming you're calling form_for on this model often from many different views and every form is going to have the same set of

问题 I wrote an api call with form builder which creates two date fields. The idea is to choose two dates and return results from db of data in that date range. I can't find where the problem is but I think the syntax in query builder is not right. I don't get any errors just an empty array.
