Getting Bad Request 400 when sending data to django rest framework through axios

Question

I am trying to make a web application in which django with django-rest-framework serves APIs and Vuejs2 is used for frontend purposes.

Here is models.py

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)

serializers.py

class ClientEntrySerializer(serializers.HyperlinkedModelSerializer):
  class Meta:
    model = ClientEntry
    fields = ('url', 'id', 'parent_name','student_name', 'tutor_name',
      'mode_payment', 'amount_recieved_parent', 'payment_mode_parent',
      'date_payment_parent', 'amount_payed_tutor', 'payment_mode_tutor', 
      'date_payment_tutor', 'payment_status', 'tuition_status', 
      'payment_due_date')

views.py

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

Here are three of the vue components which are directly related to my question

DashboardDetail.vue

export default {
  name: 'DashboardDetail',

    DashboardDetailEdit,
    DashboardDetailPost

    }
  },

        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

        this.paymentEntry.url = this.entry.url
      return this.paymentEntry

  }
}
</script>

DashboardDetailPost.vue

<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,

          date_payment_tutor: data.datePaymentTutorArray
        }
      })
      .then(() => {
        this.$refs.dashDetailForm.resetForm()
      })
      .catch((error) => {
        console.log(error)
      })
    }
  },
  created () {
    this.clonePaymentEntry = this.paymentEntry
  }
}
</script>

DashboardDetailForm.vue

export default {
  components: {
    FormDropdown,
    FormInput
  },
  name: 'DashboardDetailForm',
  props: {
    editDetailForm: Object,
    paymentEntry: Object
  },
  data () {
    return {
      showForm: false,
      form: {
        amountRecievedParent: null,
        paymentModeParent: '',
        datePaymentParent: '',
        amountPaidTutor: null,

        { 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>

Now my form property object of DashboardDetailForm component is getting values correctly and it is getting passed to DashboardDetailPost correctly as well

But when I run addPaymentEntry() method which contains axios block for PUT request I am always getting Bad Request Error in django

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

Initially my amount_recieved_parent was a PositiveIntegerField and I got the same error so I changed it to CharField after flushing database but it didn't changed anything. I am completely out of ideas to try and not been able to solve this error.

Answer 1

Linova answered the question in the comments. "the network tab allows you to view the request/response content". In my case I was getting the 400 Bad Request error in Google Chrome console, but I didnt know where to get detailed information about what went wrong.

Checking in the network tab, I was able to see more details on the request/response and I hence was able to know what to do.

This also worked for the author of the question @fluk3r as shown in the comments
