I need to use RESTful input to my Rails app. First I'm trying to just understand REST and I'm using WizTools RestClient on my MAC for testing.
I have a table called priorities and I'm trying to update a field called prioritydesc.
This is the info I'm using
METHOD = PUT
URL = http://mywebsite/priorities/4
HEADER = prioritydesc
VALUE = "TEST"
The results I'm getting is:
HTTP/1.0 501 Not Implemented
If I use the resttesttest.com site, I get:
Origin http://resttesttest.com is not allowed by Access-Control-Allow-Origin.
Thanks for the help!
UPDATE1:
Do I need gem "oauth-plugin"?
UDPATE2:
This is my priorities_controller PUT:
# PUT /priorities/1
# PUT /priorities/1.json
def update
#priority = Priority.find(params[:id])
respond_to do |format|
if #priority.update_attributes(params[:priority])
format.html { redirect_to #priority, notice: 'Priority was successfully updated.' }
format.json { head :ok }
else
format.html { render action: "edit" }
format.json { render json: #priority.errors, status: :unprocessable_entity }
end
end
end
UPDATE3
I tried on localhost using:
METHOD = PUT
URL = http://localhost/priorities/1
HEADER = prioritynum
VALUE = 5
And got
"<html><body>You are being redirected.</body></html>"
That seems OK to me.
But, the value didn't update.
UPDATE4
I used this:
METHOD = POST
URL = http://localhost/priorities
HEADER = prioritynum
VALUE = 5
And it added a new record! But, the prioritynum was blank
I also tried using
http://localhost:5000/priorities?prioritynum=5
Should the data field(s) like (prioritynum=5) be in the header or the body?
I put this in the body and it didn't work:
typecode="test"
UPDATE5
OK this worked !!
METHOD = PUT
URL = http://mywebsite/priorities?priority[prioritynum]=5
I got it working for the types controller - I used this:
Method = POST
URL = http://mywesite/types?type[typecode]=test&type[typedesc]=test%20description

I need to parse Json data from curl request.Need to split Mac,Parameter,datatype,value from below curl request and pass those data's as input for set method(For each Mac separately).Can anyone please guide how to split?
curl -k -s -H "Content-Type: application/json" -d '{"Data": {"Mac":"10.43.33.34","Parameter":"Device.wifi","datatype":"string","value":"5Ghz"},{"Mac":"15.23.43.48","Parameter":"Device.wifi","datatype":"string","value":"2.4GHZ"}}' http://test:3000/api/executions_api_set/
Set API
def show
client = SetClient.new
versionResponse = client.set_req(mac,parameter,datatype,value)
if versionResponse.code == "200"
value = JSON.parse(versionResponse.body)
render json: {Mac: mac,Response:value}, status: :ok
else
render json: {Mac: mac,Parameter: parameter,status: 'Failed',responsecode:versionResponse.code}, status: :ok
end
end
end
end
end
Updated Code
def create
value = ''
client = SetClient.new
params["Data"].each do |mac_attributes|
#mac_address, #Parameter, #dataType, #value = mac_attributes.values_at("Mac", "Parameter", "datatype", "value")
#versionResponse = client.set_req_api(#mac_address,#Parameter,#dataType,#value)
puts "versionResponse.status_code #{#versionResponse.code}"
end
if #versionResponse.code == "200"
value = JSON.parse(#versionResponse.body)
render json: {Mac_address: #mac_address,Response:value}, status: :ok
else
render json: {Mac_address: #mac_address,Parameter:#Parameter,status: 'Failed',responsecode:#versionResponse.code}, status: :ok
end
end
end
end
I'm not entirely sure what you're trying to do, but if you want the controller to call a method for each JSON object in the array, it would look something like:
def show
params["Data"].each do |hash_of_mac_attributes|
mac, parameter, datatype, value = hash_of_mac_attributes.values_at("Mac", "Parameter", "datatype", "value")
method_you_want_to_call(mac, parameter, datatype, value)
end
This is assuming that rails is correctly detecting and parsing the JSON body into the params hash for you. If it's not, that's a separate issue that can be addressed.
UPDATE
In order to return the result from each call to the external service we need to store each call in an array and render the array in the response. Something like the following:
def show
json_array = params["Data"].map do |hash_of_mac_attributes|
mac, parameter, datatype, value = hash_of_mac_attributes.values_at("Mac", "Parameter", "datatype", "value")
response = client.set_req_api(mac, parameter, datatype, value)
build_json_for_mac_lookup(response: response, mac: mac, parameter: parameter)
end
render json: json_array
end
def build_json_for_mac_lookup(arguments:, mac:, parameter:)
json_body = {Mac_address: mac}
if response.code == "200"
json_body.merge(Response: JSON.parse(response.body))
else
json_body.merge(Parameter: parameter, status: 'Failed', responsecode: response.code)
end
end
Currently, I have some QueuedImages that become GalleryImages once certain conditions are met.
#image = GalleryImage.new(image_params.except(:tags))
#image.user = current_user
#queued = QueuedImage.new(user: current_user)
#queued.image = #image
Before saving this method, transform the images into JSON:
def image_to_json
self.image_data = #image.to_json(include: :plain_images)
end
I'm trying to update the serialized hash/JSON like this:
def update
#queued = QueuedImage.find(params[:id])
hash_as_string = #queued.image_data
i_data = JSON.parse(hash_as_string.gsub('=>', ':'))
i_data["title"] = params["title"]
i_data["description"] = params["description"]
i_data["folder_id"] = params["folder_id"]
i_data["nsfw"] = params["nsfw"]
i_data["tags"] = params["tags"]
#queued.image_data = i_data
if #queued.save
render json: #queued, scope: current_user
else
render json: #queued.errors.as_json(full_messages: true), scope: current_user, status: :unprocessable_entity
end
end
Which throws me a parse error, what am I doing wrong?
How can I properly update the serialized string?
The thing is that when it transforms from a QueuedImage to a GalleryImage, another method takes that data and evaluates it and creates the new GalleryImage, so it has to be in the exact format, and I believe what I'm doing in the update method is wrong, even though I save it as a string in the DB.
I am limiting to 1, so I thought it would simple return an object in this case the same as .find_by_email
Code:
# GET /users/:identified/type/:social_type
# Returns a single record - so limit 1
def find
#user = User.where("identified = ? AND social_type = ?", params[:identified], params[:social_type]).limit(1)
if not #user.empty?
render json: #user.as_json, status: :created
else
render json: #user, status: :not_found
end
end
Current Response:
[{"id":7,"voy_num":null,"voy_pin":null}]
How can ensure I return a single JSON object?
To get the single object, use first with where like this:
#user = User.where("identified = ? AND social_type = ?", params[:identified], params[:social_type]).first
i m trying to implement a service that displays data in geojson format.
I hit my database with this :
sql =
"select ST_AsGeoJSON(boundaries)
from cluster_shapes
where category = '#{params[:category]}'
and area_id =
(select id
from areas
where name = '#{params[:city]}' )"
connection = ActiveRecord::Base.connection
#clusters = ActiveRecord::Base.connection.execute(sql)
respond_to do |format|
format.json { render json: #clusters }
end
And I get ugly results that is not valid geojson
[
{
st_asgeojson: "{"type":"Polygon","coordinates":[[[23.819537,38.039409],[23.81892,38.04068],...}"
,
st_asgeojson: "{"type":"Polygon","coordinates":[[[23.919537,38.039409],[22.81892,38.04068],...}"
,
...
If I remove the ugly part st_asgeojson and make it look like this , it is valid geojson.
{"type":"Polygon","coordinates":[[[23.819537,38.039409],[23.81892,38.04068],[23.820912,38.040237],[23.8209752169298,38.0400047630785],[23.8209519774174,38.0399755885062],[23.8205266,38.0394558],[23.819537,38.039409]]]}
So the question is how do i get rid of "st_asgeojson" ,or am i doing it wrong ?
PS:A model exist, if query is modified the result is pretty the same.
It seems like what you want is simply nested inside your #clusters json, so you can simply parse it out...
instead of:
format.json { render json: #clusters }
you should change it to
format.json { render json: #clusters[0].st_asgeojson }
Or if you are expecting more than one result to be returned from you sql query, try
format.json { render json: #clusters.map {|x| x.st_asgeojson }}
I Have a remote link that when clicked sends an ajax request to a controller action in the background. This request creates a new database entry. The problem is that it currently writes to the database 5 times for each click.
Here is my link and controller action:
click
def track_link
y = cookies[:user_email]
x = User.where(email: y).first
z = x.id
name = params[:link_name]
w = Link.new
w.name = name
w.user_id = z
w.save
respond_to do |format|
format.js { render action: "index" }
end
end
Your jquery_ujs file is probably being included 5 times.
