通过axios向Django rest framework发送数据时收到错误的请求400

Question

我试图制作一个web应用程序，其中django和django rest框架为api服务，Vuejs2用于前端目的。在

给你模型.py在

class ClientEntry(models.Model):
  id = models.AutoField(primary_key=True)
  parent_name = models.CharField(
    max_length=30,
    blank=False,
    help_text="Enter parent's name"
  )
  student_name = models.CharField(
    max_length=30,
    blank=True,
    help_text="Enter student's name"
  )
  tutor_name = models.CharField(
    max_length=30,
    blank=False,
    help_text="Enter tutor's name"
  )
  mode_payment = models.CharField(
    "mode of payment",
    max_length=30,
    blank=False,
    help_text="how are we getting paid"
  )
  amount_recieved_parent = ArrayField(
    models.CharField(
      max_length=30
    ),
    blank=True,
    null=True
  )
  payment_mode_parent = ArrayField(
    models.CharField(
      max_length=30
    ),
    blank=True,
    null=True
  )
  date_payment_parent = ArrayField(
    models.DateField(),
    blank=True,
    null=True
  )
  amount_payed_tutor = ArrayField(
    models.CharField(
      max_length=30
    ),
    blank=True,
    null=True
  )
  payment_mode_tutor = ArrayField(
    models.CharField(
      max_length=30
    ),
    blank=True,
    null=True
  )
  date_payment_tutor = ArrayField(
    models.DateField(),
    blank=True,
    null=True
  )
  payment_status = models.CharField(
    max_length=30,
    blank=True,
    null=True
  )
  tuition_status = models.CharField(
    max_length=30,
    blank=True,
    null=True
  )
  payment_due_date = models.DateField(
    blank=True,
    null=True
  )
  class Meta:
    ordering = ['id']
    verbose_name_plural = "Client entries"

  def __str__(self):
    return str(self.parent_name)

在序列化程序.py在

^{pr2}$

在视图.py在

class ClientEntryViewSet(viewsets.ModelViewSet):
  queryset = ClientEntry.objects.all()
  serializer_class = ClientEntrySerializer

下面是与我的问题直接相关的三个vue组件

在仪表板详细信息.vue在

export default {
  name: 'DashboardDetail',
  components: {
    DashboardDetailEdit,
    DashboardDetailPost
  },
  data () {
    return {
      entry: {},
      paymentEntry: {
        url: '',
        amountRecievedParentArray: [],
        paymentModeParentArray: [],
        datePaymentParentArray: [],
        amountPaidTutorArray: [],
        paymentModeTutorArray: [],
        datePaymentTutorArray: []
      }
    }
  },
  methods: {
    getEntry() {
      axios({
        method: 'get',
        url: 'http://127.0.0.1:8000/api/dashboard/' + this.$route.params.id + '/'
      }).then(response => this.entry = response.data);
    }
  },
  created () {
    this.getEntry()
  },
  computed: {
    paymentEntryComputed: function () {
      if (this.entry !== null && this.entry.hasOwnProperty("amount_recieved_parent") && this.entry.amount_recieved_parent !== null)
        this.paymentEntry.amountRecievedParentArray = this.entry.amount_recieved_parent
      if (this.entry !== null && this.entry.hasOwnProperty("payment_mode_parent") && this.entry.payment_mode_parent !== null)
        this.paymentEntry.paymentModeParentArray = this.entry.payment_mode_parent
      if (this.entry !== null && this.entry.hasOwnProperty("date_payment_parent") && this.entry.date_payment_parent !== null)
        this.paymentEntry.datePaymentParentArray = this.entry.date_payment_parent
      if (this.entry !== null && this.entry.hasOwnProperty("amount_payed_tutor") && this.entry.amount_payed_tutor !== null)
        this.paymentEntry.amountPaidTutorArray = this.entry.amount_payed_tutor
      if (this.entry !== null && this.entry.hasOwnProperty("payment_mode_tutor") && this.entry.payment_mode_tutor !== null)
        this.paymentEntry.paymentModeTutorArray = this.entry.payment_mode_tutor
      if (this.entry !== null && this.entry.hasOwnProperty("date_payment_tutor") && this.entry.date_payment_tutor !== null)
        this.paymentEntry.datePaymentTutorArray = this.entry.date_payment_tutor
      if (this.entry !== null && this.entry.hasOwnProperty("url"))
        this.paymentEntry.url = this.entry.url
      return this.paymentEntry
    }
  }
}
</script>

在DashboardDetailPost.vue在

<template>
  <dashboard-detail-form @submit-query="addPaymentEntry"
  :paymentEntry="clonePaymentEntry"
  ref="dashDetailForm"></dashboard-detail-form>
</template>

<script>

export default {
  components: {
    DashboardDetailForm
  },
  name: 'DashboardDetailPost',
  props: {
    paymentEntry: Object
  },
  data(){
    return {
      clonePaymentEntry: {}
    }
  },
  methods: {
    addPaymentEntry (data) {
      axios({
        method: 'put',
        url: this.paymentEntry.url,
        data: {
          amount_recieved_parent: data.amountRecievedParentArray,
          payment_mode_parent: data.paymentModeParentArray,
          date_payment_parent: data.datePaymentParentArray,
          amount_payed_tutor: data.amountPaidTutorArray,
          payment_mode_tutor: data.paymentModeTutorArray,
          date_payment_tutor: data.datePaymentTutorArray
        }
      })
      .then(() => {
        this.$refs.dashDetailForm.resetForm()
      })
      .catch((error) => {
        console.log(error)
      })
    }
  },
  created () {
    this.clonePaymentEntry = this.paymentEntry
  }
}
</script>

在仪表板详细信息窗体.vue在

export default {
  components: {
    FormDropdown,
    FormInput
  },
  name: 'DashboardDetailForm',
  props: {
    editDetailForm: Object,
    paymentEntry: Object
  },
  data () {
    return {
      showForm: false,
      form: {
        amountRecievedParent: null,
        paymentModeParent: '',
        datePaymentParent: '',
        amountPaidTutor: null,
        paymentModeTutor: '',
        datePaymentTutor: ''
      },
      paymentModeArray: [
        { value: "cash", text: "Cash" },
        { value: "paytm", text: "PayTM" },
        { value: "bank seth", text: "Bank Seth" },
        { value: "bank anuj", text: "Bank Anuj" },
        { value: "kotak", text: "Kotak" }
      ]
    }
  },
  created () {
    if (typeof this.editDetailForm !== "undefined") {
      this.form.amountRecievedParent = this.editDetailForm.amountRecievedParent
      this.form.paymentModeParent = this.editDetailForm.paymentModeParent
      this.form.datePaymentParent = this.editDetailForm.datePaymentParent
      this.form.amountPaidTutor = this.editDetailForm.amountPaidTutor
      this.form.paymentModeTutor = this.editDetailForm.paymentModeTutor
      this.form.datePaymentTutor = this.editDetailForm.datePaymentTutor
    }
  },
  methods: {
    formToggle () {
      this.showForm = !this.showForm
    },
    resetDetailForm () {
      this.form.amountRecievedParent = null,
      this.form.paymentModeParent = '',
      this.form.datePaymentParent = '',
      this.form.amountPaidTutor = null,
      this.form.paymentModeTutor = '',
      this.form.datePaymentParent = ''
    },
    computePaymentEntry () {
      this.paymentEntry.amountRecievedParentArray.push(this.form.amountRecievedParent)
      this.paymentEntry.paymentModeParentArray.push(this.form.paymentModeParent)
      this.paymentEntry.datePaymentParentArray.push(this.form.datePaymentParent)
      this.paymentEntry.amountPaidTutorArray.push(this.form.amountPaidTutor)
      this.paymentEntry.paymentModeTutorArray.push(this.form.paymentModeTutor)
      this.paymentEntry.datePaymentTutorArray.push(this.form.datePaymentTutor)
      this.validateBeforeSubmit()
    },
    validateBeforeSubmit () {
      this.$validator.validateAll().then(() => {
        if(!this.errors.any()) {
          this.$emit('submit-query', this.paymentEntry)
          this.formToggle()
        }
      })
    }
  }

}
</script>

现在我的DashboardDetailForm组件的表单属性对象正确地获取了值，并且也正确地传递给了DashboardDetailPost

但是，当我运行addPaymentEntry（）方法时，它包含用于PUT请求的axios块，我总是在django中得到错误的请求

Bad Request: /api/dashboard/1/
[05/Nov/2018 20:50:27] "PUT /api/dashboard/1/ HTTP/1.1" 400 414

最初，我的amount_received_parent是一个PositiveIntegerField，我得到了同样的错误，所以我在刷新数据库后将其更改为CharField，但它没有改变任何东西。我完全没有办法试着解决这个错误。在

利诺娃在评论中回答了这个问题。”“网络”选项卡允许您查看请求/响应内容”。在我的例子中，我在googlechrome控制台中收到了400个Bad请求错误，但是我不知道从哪里可以得到关于出错的详细信息。在

在network选项卡中，我可以看到关于请求/响应的更多细节，因此我能够知道该怎么做。在

这也适用于问题@fluk3r的作者，如评论中所示
