I have this url encoded:
Started PUT "/path/thing/9812/close?status=close&shutdown_on=2018-12-05%2010%3A08%3A06&affected_external_id=15027&fqdns%5B0%5D=150.212.3.249"
which decoded is this:
"/path/thing/9812/close?status=close&shutdown_on=2018-12-05 10:08:06&affected_external_id=15027&fqdns[0]=150.212.3.249"
I get this parameters:
Parameters: {"status"=>"close", "shutdown_on"=>"2018-12-05 10:08:06", "affected_external_id"=>"15027", "fqdns"=>{"0"=>"150.212.3.249"}, "id"=>"9812"}
How can get fqdn as a array? on Rails 4
You should do the following:
params[:fqdns].to_a
Doing this, will produce the following:
{['0', '150.212.3.249', ...]}
If you wnat only the values, may you can try:
params[:fqdns].values
Doing this, will give you the following:
['150.212.3.249', ...]
But for this, you have to do it inside a ruby class, i strongly recommends you to do it inside your controller. Hope i can help.
UPDATE
After a recommends, you can do it with strong parameters, permiting the param fqdns as a hash (because you route receiving a hash):
def resource_params
params.permit(....., fqdns: {})
end
After this, you already have to execute the solutions above to get fqsnd as a array
In Play if I want to get the string form of the route how do I get that from the controller and method declaration?
eg
Application.home()
Check out https://www.playframework.com/documentation/1.4.x/routes#reverse
String url = Router.reverse("Application.home").url;
I'm new to node and unable to create a simple route which will include regex as on of the parameter
// student.js - route file for route /student
app.get('/student/:/^[a-z0-9-]+$/', function(req,res){
res.send('student found');
});
when i hit localhost:3000/student/student-slug it says Cannot GET /student/student-slug
two more question
1) how to get param which is of regex, usually we can do this var _student = res.param.student_name but i'm unable to think for the regex
2) how to set optional param, let's say for pagination, route is like
/list/students/ will show list of last x student but /list/students/48 will offset that value to 48th row
this question may be duplicate but i'm unable to find answer
You need to encode the uri string before pass to request and decode it in your route handler.
Usage is very clear:
encodeURIComponent(str);
And for decoding use:
decodeURIComponent(str);
check the official documentation here

I'm trying to get autocomplete working in my rails application using Magic Suggest.
I think this is the correct question: How can I get MagicSuggest to grab the JSON that is at the URL I give it?
This is the error that console returns when I type letters:
POST http://localhost:3000/search_foods 404 (Not Found) jquery.js:8706
Uncaught Could not reach server
Here's the magic suggest code:
input.magicSuggest({
data: "/foods/search/",
placeholder: "Search Foods...",
valueField:'idFood',
displayField:'foodName'
});
The Routes
resources :search_foods
The Controller and Action
class SearchFoodsController < ApplicationController
def index
render json: %['Crack', 'Cocain', 'Gorilla Test', 'Horse Test']
end
end
When I visit the /search_foods url directly I get
'Crack', 'Cocain', 'Gorilla Test', 'Horse Test'
as my code is designed to do.
I think the issue is in that MagicSuggest, by default, sends a POST request, although I'm not sure if that's entirely relevant:
You can pass the url from which the component will fetch its JSON data.Data will be fetched
* using a POST ajax request that will * include the entered text as 'query' parameter. The results
* fetched from the server can be:
* - an array of JSON objects (ex: [{id:...,name:...},{...}])
* - a string containing an array of JSON objects ready to be parsed (ex: "[{id:...,name:...},{...}]")
* - a JSON object whose data will be contained in the results property
* (ex: {results: [{id:...,name:...},{...}]
Try this:
input.magicSuggest({
data: "http://localhost:3000/search_foods",
placeholder: "Search Foods...",
valueField:'idFood',
displayField:'foodName'
});
The doc states that the component expects one of the following:
* - an array of JSON objects (ex: [{id:...,name:...},{...}])
* - a string containing an array of JSON objects ready to be parsed (ex: "[{id:...,name:...},{...}]")
* - a JSON object whose data will be contained in the results property
* (ex: {results: [{id:...,name:...},{...}]
When you visit /search_foods you get
'Crack', 'Cocain', 'Gorilla Test', 'Horse Test'
This does not fit any of the 3 supported cases.
My suspicions about the POST request was correct.
My friend helped out so that's why I was able to fix this.
This is what I did..
Eliminated the FoodSearch Controller, because that's not needed at all.
Created a search action in my Food Controller like so:
def search
render json: ['cocain', 'crack', 'gorilla testosterone']
end
Edited my routes to a POST request instead of a get *This was the key:
resources :foods do
collection do
post :search
end
end
--- Another option, as karlipoppins suggests, is to simply change the type of request that magicSuggest makes by including the method attribute like so:
input.magicSuggest({
method: 'get',
data: "/foods/search/",
placeholder: "Search Foods...",
valueField:'idFood',
displayField:'foodName'
});
Then I wouldn't need to change the route to post.
Added this path to the data attribute in the js
data: "/foods/search/"
This will be a huge help to anyone trying to get magicSuggest to work in rails. It's a pretty damn easy setup to be honest. That one bit and the JSON formatting was the only thing that was tripping me up here.
I created a small app that takes a search query and returns mock content. You can see the app here: http://embersherpa.com/wip/search-example/app/#/search
It work correctly when entering the query via the search but not via the url.
How do I correctly handle search queries with "/" when entered via url?
You should probably not put your keyword directly into the URL. Instead escape it first with encodeURIComponent and unescape it with decodeURIComponent in your model hook. The rough code look like this:
serialize : function(model){
// model is the keyword in your case
return {keyword: encodeURIComponent(model)};
},
model : function(params){
var keyword = decodeURIComponent(params.keyword);
// do what you need to do with the keyword
}
