lightning:inputfield checkbox not saving

Question

According tot he documentation, lightning:inputfield should work for checkbox type field.

Here is a snapshot of the code we have:

<aura:attribute name="dealershiptTeamRecord" type="IMP_Dealership_Team_Info__c" /> 

<force:recordData aura:id="recordHandler"
                      recordId="{!v.recordId}"
                      targetFields="{!v.dealershiptTeamRecord}"
                      recordUpdated="{!c.handleRecordChange}"
                      mode="EDIT"
                      fields="IMP_Team_Closed_Friday__c"
/>

<lightning:recordEditForm aura:id="recordViewForm"
    recordId="{!v.recordId.Id}"
    recordTypeId="{!v.recordId.RecordTypeId}"
    objectApiName="IMP_Dealership_Team_Info__c"
    onload="{!c.handleRecordChange}">

        <lightning:inputField   fieldName="IMP_Team_Closed_Monday__c" 
                                value="{!v.dealershiptTeamRecord.IMP_Team_Closed_Monday__c}" />
</lightning:recordEditForm>

Where IMP_Team_Closed_Monday__c is a checkbox field type,

In our case, the form, when saved, always sets the value to false not matter what the checkbox in the UI is set.

Answer 1

Your <lightning:recordEditForm> isn't receiving the correct sObject Id.

recordId="{!v.recordId.Id}"

should be

recordId="{!v.recordId}"

Answer 2

Try using lightning:recordForm in edit mode, without layout type and specifying only that custom field in fields attribute.
