Django POST sub-dictionaries - django

I'm making the following request through command-line cURL:
curl -X POST http://localhost:8000/api/places/ -vvvv -d "place[name]=Starbucks"
However, when I try to access the parameters by calling
request.POST.getlist('place')
I get an empty array as a response. How can I access the sub-dictionary which I can then pass to the ORM?
Thanks,
Jamie

HTTP data elements can't have sub-elements. The data you have posted - as shown in the querydict - has been interpreted as a single element with key "place[name]" and value "Starbucks". So you can get it with request.POST["place[name]"].

It looks like you are sending a string, in that case try:
request.POST.get('place[name]')
If your are simulating a dropdown list you should send "place=Starbucks", however if you are trying to send an array you should try to convert you string to an array inside your python script.
In your command you can get ride of "-X POST" as the parameter -d is already an HTTP POST:
curl --help
...
-d/--data <data> HTTP POST data (H)

category_list param for test page creation request

Having created a test user for my app, I intend to create a test page by sending the following POST request to the Facebook API (some parts obviously replaced with dummies):
https://graph.facebook.com/v7.0/<TEST_USER_ID>/accounts?access_token=<APP_TOKEN>&name=Dummypage&category_enum=BANK&about="Text"&picture=<URL_TO_IMAGE>&cover_photo={"url": "<URL_TO_OTHER_IMAGE>"}&location={"city": "SomeCity","state": "SomeState","country": "DE"}&address="<ADDRESS>"&phone="<PHONE>"&category_list=[{"id": "133576170041936"} ,{"id": "145988682478380"}]
The problematic part of this is the category_list parameter, which I have attempted to pass in many forms already. Arriving at
category_list=[{"id": "133576170041936"} ,{"id": "145988682478380"}]
I finally no longer get the error that the param has to be an array - instead I get the following error: (#100) Param category_list[0] must be a valid ID string (e.g., \"123\") .
This is fairly confusing, as the IDs are taken from the response of an API response containing the page categories:
https://graph.facebook.com/v7.0/fb_page_categories?access_token=<TOKEN>
How should the parameter be correctly passed?
What I tried so far:
category_list=["145988682478380"]
category_list=[145988682478380]
Result: (#100) Invalid parameter
category_list=[{"id": "145988682478380"}]
category_list=[{"id": "145988682478380", "name": "Kreditgenossenschaft", "api_enum": "CREDIT_UNION"}] #full entry as listed in page categories response
Result: (#100) Param category_list[0] must be a valid ID string (e.g., "123")

Creating a test page via POST request
This curl command worked by me:
curl -i -X POST -H "Content-Type: application/json" -d "{ \"category_list\": [192803624072087, 145988682478380]}" "https://graph.facebook.com/v8.0/me?access_token=[page_access_token]"
So with the following JSON Body:
{
"category_list": [192803624072087, 145988682478380]
}

Unable to query through elasticsearch

I am using Elasticsearch in my Django application. When i try to query my result using curl i get found = false. Can someone help me here !]1
I am following this tutorial and my code when i execute https://www.freecodecamp.org/news/elasticsearch-with-django-the-easy-way-909375bc16cb/ and my code fails when i execute
curl -XGET 'localhost:9200/blogpost-index/blog_post_index/1?pretty'
The above method is for fetching the document by its id. As per the JSON response of the ES server, document with id 4 doesn't exist. You can possibly try to fetch all documents by using match_all query on the index to fetch all the documents and see if the document you are trying to see exists.
Here's the CURL syntax:
curl -X GET "localhost:9200/_search" -H 'Content-Type: application/json' -d'
{
"query": {
"match_all": {}
}
}
'
Reference : Match All Query
You can also see the range of documents IDs to see if the document you are trying to fetch, exists.

Pass dynamic value to url in Postman

I have 2 requests
1st Request
After did my first request, I get the response where I can parse for a taskId
In my test tab, I will then parse and store it like this
let taskId = pm.response.json().body.result[0].data.task
console.log(taskId)
I can see taskId printing in my console as 938
2nd Request
I require making a GET with this dynamic URL with the taskId that I got from the first one
http://localhost:3000/fortinet/monitor/{{taskId}}
So I set the above URL , set the HTTP verb to GET
in my Pre-request Script tab, I did this
let taskId = pm.globals.get("taskId")
Result
ReferenceError: taskId is not defined
Image Result
How can I debug this further?
The most suggested way is to use :key as in
http://localhost:3000/fortinet/monitor/:taskId
See the colon before taskId. The reason being, URI values sometimes many not be environment dependent. So, based on the usecase, you can use like I said or {{taskId}}
You have to set variable, but you are doing it wrong.
try this:
pm.globals.set("taskID", pm.response.json().body.result[0].data.task)
more you can read here:
https://learning.postman.com/docs/postman/variables-and-environments/variables/
Please note, that URL which ends with resource identified like https://example.com/:pathVariable.xml or https://example.com/:pathVariable.json will not work.
You can go with https://example.com/:pathVariable with Accept: application/json header.
For passing dynamic value, first you have to set it in environment or global variable in Tests tab because tests runs after request and you will get response value after request sent, but because you get response in json you have to first parse it, so what you can write in Tests tab is as follows:
var jsonData = JSON.parse(responseBody);
postman.setEnvironmentVariable("taskId", jsonData.token); // OR
postman.setGlobalVariable("taskId", jsonData.token);
Then you can use taskId as {{taskId}} wherever you want in url parameters or in request body or form data wherever.
If you want to know in detail how to extract data from response and chain it to request then you can go to this postman's official blog post which is written by Abhinav Asthana CEO and Co Founder of Postman Company.

Graphene Django "Must provide query string"

I have setup a Graphene server using Django. When I run my queries through GraphiQL (the web client), everything works fine. However, when I run from anywhere else, I get the error: "Must provide query string."
I did some troubleshooting. GraphiQL sends POST data to the GraphQL server with Content-Type: application/json. Here is the body of the request that I copied from Chrome network tab for GraphiQL:
{"query":"query PartnersQuery {\n partners{\n name\n url\n logo\n }\n}","variables":"null","operationName":"PartnersQuery"}
When I copy it to Postman with Content-Type: application/json, I get the following response:
{
"errors": [
{
"message": "Must provide query string."
}
]
}
What can be the cause of this problem? I have not done anything crazy with the schema. Just followed the tutorials from graphene's docs. What else can cause an issue like this?
This error is raised when parse_body is unable to parse the incoming data. I'd start there by looking at the data passed into this method and ensuring it's of the correct type.
For example, the multipart/form-data section naively returns request.POST, which may need to be overwritten to handle, for example, the request that apollo-upload-client sends for file upload handling.
In our case we created a view to both require a login and to support the apollo-upload-client use case and it works fine.
Here's how I was able to get a successful response from Postman using a graphene Django backend with a simple mutation:
Set method to POST
Add the URL to your graphQL endpoint, e.g. http://localhost:8000/api/
Add one header -- key: "Content-Type" , value: "application/json"
Set the body to "raw"
Paste in your query into the body window, e.g. {"query":"{myModels {id}}","variables":"null","operationName":null}
This sounds pretty much like what you did, so you must be close.
I faced the same problem when I try to used graphQl query using POSTMAN,
In POSTMAN send data in row with json type.
You have to make json data grapQl query and mutations data like this
Query Command:
{"query":"{user(id:902){id,username,DOB}}"}
Mutations Command:
{ "query": "mutation {createMutations(reviewer:36, comments:\"hello\",loan: 1659, approved: true ){id}}" }
#commnent: String Type
#data_id:Int Type
#approved:Boolean Type
Checkout sample apps and see how they do things,
e.g.
https://github.com/mjtamlyn/graphene-tutorial
they do the following:
from django.views.decorators.csrf import csrf_exempt
from graphene_django.views import GraphQLView
url(r'^explore', GraphQLView.as_view(graphiql=True)),
url(r'^graphql', csrf_exempt(GraphQLView.as_view())),
I encountered exactly the same problem as the original poster, Gasim. Studying the code in 'graphiql.html' I see that they're converting the query string, that goes into the body, into the query parameter in the URL. Thus you end up with this URL being sent via Postman:
http://127.0.0.1:8000/graphql?query=%7B%0A%20%20allCategories%20%7B%0A%20%20%20%20edges%20%7B%0A%20%20%20%20%20%20node%20%7B%0A%20%20%20%20%20%20%20%20name%0A%20%20%20%20%20%20%20%20ingredients%20%7B%0A%20%20%20%20%20%20%20%20%20%20edges%20%7B%0A%20%20%20%20%20%20%20%20%20%20%20%20node%20%7B%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20name%0A%20%20%20%20%20%20%20%20%20%20%20%20%7D%0A%20%20%20%20%20%20%20%20%20%20%7D%0A%20%20%20%20%20%20%20%20%7D%0A%20%20%20%20%20%20%7D%0A%20%20%20%20%7D%0A%20%20%7D%0A%7D%0A
It seems nonsensical to me to duplicate precisely what's in the body in the query string in the URL too but that appears to be the only way to get the Graphene server to return a valid response.
Surely this is a bug/shortcoming that will be fixed?

Enable graphine on django
url(r'^graphql', csrf_exempt(GraphQLView.as_view(graphiql=settings.DEBUG))),
Execute some query and see it is working
On Chrome browser, go to graphiQL endpoint: http://localhost:8000/graphql? open "Developer Tools" in browser and go to "Network" tab.
Execute your query again. Now it appears on list of requests. Now right mouse click on it and copy it "copy as CURL". Now you can strait copy paste it to linux terminal with curl installed. Or like in your case you can try to deduct what is what there, and try to reuse it in your IDE like client like Insomnia or Postman. For instance you may discover that authorisation that works with session on graphiQL enpoint, is not what you want at the end...
curl 'http://localhost:8000/graphql?' -H 'Origin: http://localhost:8000' -H 'Accept-Encoding: gzip, deflate, br' -H 'Accept-Language: en-US,en;q=0.9,pl;q=0.8,de;q=0.7' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36' -H 'Content-Type: application/json' -H 'Accept: application/json' -H 'Cookie: _ga=GA1.1.1578283610.1528109563; _gid=GA1.1.920024733.1541592686; csrftoken=EGBeegFoyMVl8j1fQbuEBG587nOFP2INwv7Q0Ee6HeHHmsLOPUwRonzun9Y6pOjV; sessionid=4u9vngcnmjh927a9avpssvc4oq9qyqoe' -H 'Connection: keep-alive' -H 'X-CSRFToken: EGBeegFoyMVl8j1fQbuEBG587nOFP2INwv7Q0Ee6HeHHmsLOPUwRonzun9Y6pOjV' --data-binary '{"query":"{\n allStatistics(projectId: 413581, first:25) {\n pageInfo {\n startCursor\n endCursor\n hasPreviousPage\n hasNextPage\n }\n edges {\n cursor\n node {\n id\n clickouts\n commissionCanc\n commissionConf\n commissionLeads\n commissionOpen\n eventDate\n extractTstamp\n hash\n leads\n pageviews\n projectId\n transactionsCanc\n transactionsConf\n transactionsOpen\n }\n }\n }\n}\n","variables":null,"operationName":null}' --compressed
The problem in my code was that I had the URL improperly setup for graphQL. I had the following:
url(r'^graphql/', GraphQLView.as_view())
The forward slash was a huge difference. Removing it fixed the problem. The proper way to do it would be:
url(r'^graphql', GraphQLView.as_view())

Jersey matches regex pattern before the method type

Is it possible to define 2 methods in Jersey with same regex but different type? (GET, PUT ..):
#GET
#Path("{key: .+}")
#Produces(MediaType.TEXT_PLAIN)
public Response root(String key) {
}
#PUT
#Path("{key: .+}")
#Consumes(MediaType.MULTIPART_FORM_DATA)
#Produces(MediaType.TEXT_PLAIN)
public Response publish(String key, FormDataMultiPart data) {
}
The first method should only reply for the key (with or without slashes)
curl -X GET "http://localhost/key
Jersey respond with 200 OK since it went to the GET method
curl -X GET "http://localhost/key/
Jersey respond with 200 OK since it went to the GET method
curl -X PUT -T file.txt "http://localhost/key
Jersey respond with 200 OK since it went to the PUT method
curl -X PUT -T file.txt "http://localhost/key/
Jersey respond with 200 OK since it went to the PUT method
curl -X PUT -T file.txt "http://localhost/key/folder/folder
Jersey respond with 405 Method Not Found since it went to the GET method
instead of the PUT (the get only respond to 1 folder level which is the 'key'
but i expected that jersey will go directly to the PUT since it suppose to check for the method type before the regex matching
Why the last one doesn't work? it seems Jersey first looks for regex even though it's a PUT request.
You say "Jersey respond with 405 Method Not Found since it went to the GET method instead of the PUT" but a 405 means that it didn't go to any method. Try changing your PUT method to:
#PUT
#Path("{key: .+}")
#Produces(MediaType.TEXT_PLAIN)
public Response publish(String key) {
}
And that should work. You then need to ensure that you provide the correct data as part of your CURL request to ensure that it matches the #Consumes annotation when you put it back in to the request.
