首先,我认为您需要检查有关具有多个输入的表单的相关 React 文档。它为您提供了关于在 React 端应该如何构建事物的基本想法。
关于从服务器获取数据,您可以在componentDidMount
以下内容中尝试以下操作:
componentDidMount() {
// Assuming you are using jQuery,
// if not, try fetch().
// Note that 2 is hardcoded, get your user id from
// URL or session or somewhere else.
$.get('/api/profile/2/', (data) => {
this.setState({
formFields: data.fields // fields is an array
});
});
}
然后你可以在render
方法中创建你的 html 输入元素,如下所示:
render () {
let fields = this.state.formFields.map((field) => {
return (
<input type="text" value={field.value} onChange={(newValue) => {/* update your state here with new value */ }} name={field.name}/>
)
});
return (
<div className="container">
<form action="">
{fields}
<button onClick={this.submitForm.bind(this)}>Save</button>
</form>
</div>
)
}
这是你的submitForm
方法:
submitForm() {
$.post('/api/profile/2/', {/* put your updated fields' data here */}, (response) => {
// check if things done successfully.
});
}

以下是untested-but-should-work
DRF 视图的示例:
from rest_framework.decorators import api_view
from django.http import JsonResponse
from rest_framework.views import APIView
class ProfileFormView(APIView):
# Assume you have a model named UserProfile
# And a serializer for that model named UserSerializer
# This is the view to let users update their profile info.
# Like E-Mail, Birth Date etc.
def get_object(self, pk):
try:
return UserProfile.objects.get(pk=pk)
except:
return None
# this method will be called when your request is GET
# we will use this to fetch field names and values while creating our form on React side
def get(self, request, pk, format=None):
user = self.get_object(pk)
if not user:
return JsonResponse({'status': 0, 'message': 'User with this id not found'})
# You have a serializer that you specified which fields should be available in fo
serializer = UserSerializer(user)
# And here we send it those fields to our react component as json
# Check this json data on React side, parse it, render it as form.
return JsonResponse(serializer.data, safe=False)
# this method will be used when user try to update or save their profile
# for POST requests.
def post(self, request, pk, format=None):
try:
user = self.get_object(pk)
except:
return JsonResponse({'status': 0, 'message': 'User with this id not found'})
e_mail = request.data.get("email", None)
birth_date = request.data.get('birth_date', None)
job = request.data.get('job', None)
user.email = e_mail
user.birth_date = birth_date
user.job = job
try:
user.save()
return JsonResponse({'status': 1, 'message': 'Your profile updated successfully!'})
except:
return JsonResponse({'status': 0, 'message': 'There was something wrong while updating your profile.'})
这是此视图的相关网址:
urlpatterns = [
url(r'^api/profile/(?P<pk>[0-9]+)/$', ProfileFormView.as_view()),
]
