在Laravel中使用vue.js获取动态字段数据

问题描述

我正在创建多个动态字段，并且将相同的内容发布到laravel控制器方法中，但是我能够获取简单字段数据（不是动态生成的字段），而是动态生成这些值的数组字段，我无法进入控制器方法。

 <input :name="'students['+studentdetails.id+']['+studentdetails.class+']'" type="text" class="form-control"/>
 <input :name="'students['+studentdetails.id+']['+studentdetails.class+']'" type="text" class="form-control"/>

在获取控制器的方法中：

  printr($request->attributes);


 export default {
  data() {
...

return {
      
      form: new Form({
        title: "",attributes: [],}),};

  addStudent() {
          const header = {
            Authorization: "Bearer " + this.token,};
          this.form
            .post(APP_URL + `/api/addStudent`,{ headers: header })
            .then((response) => {
              if (response.status == 200) {
                location.replace(APP_URL + "/success");
              } 
            });
        },};

没有价值。

解决方法

您现在正在将web: gunicorn index:server --workers 4 和Traceback (most recent call last): File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 225,in run handler() File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 260,in handle_term raise StopIteration StopIteration During handling of the above exception,another exception occurred: Traceback (most recent call last): File "/app/.heroku/python/bin/gunicorn",line 11,in <module> sys.exit(run()) File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/app/wsgiapp.py",line 61,in run WSGIApplication("%(prog)s [OPTIONS] [APP_MODULE]").run() File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/app/base.py",line 223,in run super(Application,self).run() File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/app/base.py",line 72,in run Arbiter(self).run() File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 228,in run self.halt() File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 345,in halt self.stop() File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 393,in stop time.sleep(0.1) File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 245,in handle_chld self.reap_workers() File "/app/.heroku/python/lib/python3.6/site-packages/gunicorn/arbiter.py",line 525,in reap_workers raise HaltServer(reason,self.WORKER_BOOT_ERROR) gunicorn.errors.HaltServer: <HaltServer 'Worker failed to boot.' 3> 创建为字符串，但不应创建为字符串。完全删除字符串引号，因为仅使用变量：
