Match a route only if a route param matches an enumeration value - react-router

I have two routes in react router which are of same depth.
/:category/:period
/:category/:attribute
To differentiate between one and two, I want to match the first route only if the period is one of (year|quarter|month). How do I write the route?
I tried /:category/(year|month|quarter):period
But does not seem to work. What would be the right regex so that the route is captured only when period is one of year, month, quarter. And that value is available as a route param - period. Thanks.


The following route works:
/:category/:period(year|month|quarter)

Google Maps Geocoding - Results in different order

Trying to get the state from maps.googleapis.com/maps/api/geocode/xml is not working for me because not all results are in the same order
The problem is not all locations are the same, I'm using coordinates as the parameter in the urls, most are address_component[5], but the others put the state any and ever where else. The only thing that seems consistant is the formatted address.
See these 2 examples, the states are in different order
for one $xml->result->address_component[5]->short_name is the state
for the other $xml->result->address_component[4]->short_name is the state
https://maps.googleapis.com/maps/api/geocode/xml?latlng=38.7811981,-75.6823615&sensor=false
http://maps.googleapis.com/maps/api/geocode/xml?latlng=36.370791599999996,%20-76.75601170000002&sensor=false
There has to be a simple answer! Thanks

Geocoder api returning single result

I need to Geocode all the branches of a chain within a country or state currently I am able to fetch a single result but I need to get the data for all the branches.
https://maps.googleapis.com/maps/api/geocode/json?address=macdonaldsIndia&key="MY-API-Key"
I think I am missing some extra parameters that need to be passed in the api.Please suggest if I am missing something
Thanks in advance

You should look into Places API web service. With nearby search or text search you can get up to 60 results.
For example if I search 'macdonalds India' for location 28.661898,77.227396 with radius 50km I can get 22 results. 20 results in the first page and 2 results in second page that I get using page token parameter.

Array Condition within EPA CEP PROTON

Using CEP Proton I want to check if, for the events received in a time interval, the id of the second and following events is contained in an attribute of type array coming in the first event. Let's say the first event is coming with the attribute called group that is an array of integers (10, 20, 30). The following events will come with an id, ex 20, 25 and so on. I want to check if the id of those events is included in the attribute group included in the first event.
For that I have created a condition in EPA
ArrayContains(ArrayGet(myevent.group,0),ArrayGet(myevent.id,ArraySize(myevent.id)-1))
However I'm getting an error when I click on verify
Error Error in EPA: expression error of undefined myepa
Am I doing anything wrong?
Cannot I access to the attribute array using ArrayGet? Or maybe ArrayContains cannot work with the result of ArrayGet?

Please share the whole JSON definition of your application.
From the information you have provided it is not clear which type of EPA it is (to access a series of events you need a statefull EPA and you need to make sure you write the application in such a way as to be able to distinguish between the first and subsequent events).
Additionally it is not clear why you try to access the same event instance- myevent in both parts of the expression.
ArrayContains recieves (array, value) as operands.
You pass it (value, value), and thats assuming that "myevent.id" is also an array, which from your description I understood it is not?
Anyway, I see lots of potential problems with your expression, therefore I would like to see the whole JSON, or at least the part relevant to the "myepa" EPA.

I have reviewed the JSON application, there are multiple problems:
1)You are using an EPA of type aggregate, to calculate a COUNT. Count is for counting events. It is an integer variable. No boolean values can be assigned to it.
Therefore comparison expressions like "count == true"
Or assigment of boolean values like : "count : ArrayContains(ArrayGet(gupsyupdate.neighbours,0),ArrayGet(gupsyupdate.id,ArraySize(gupsyupdate.id)-1))"
Are not valid.
2)Additionally, assuming you use this expression somewhere, and not in count variable:
-the gupsyupdate event has no attribute "id", so you cannot use this in an expression.
-ArrayGet(gupsyupdate.neighbours,0) - will return a single object within an array... So you cannot use it in ArrayContains expression which is supposed to receive an array
3)The policies of the EPA doesn't make sense... It is an aggregation EPA, but you use it with evaluationPolicy of "Immediate" and cardinality policy "Single". That means this EPA will be evaluated only once, immediately as it receives the first gupsyupdate event. So it will not really act as aggregator....
Please revise your application according to this input.

MuleESB. How to stop for each loop?

Good day, collagues.
Give me the cue, pls.
In one my case for JSON parsing i am using FOR EACH component with Choice inside him.
Like this:
After http request i have in the paylaod some JSON result, which represents of some collection. Foreach treats every item from collection and compute it's properties with condition in Choice component.
I want to stop the loop when condition in Choice was found. I don't want to compare all items of result collection.
I tried to change the variable 'counter' inside the Fore each loop. But it is not working.
May be anybody has found the way?

You may not be able to do this using a for-each. But you could always have an expression/groovy script to do this loop and breaking based on your condition. Please refer this: Is there a break statement in Mule <foreach>

how to check the google map api to know the place is existing one

I have use the code given below, please copy and paste in your URL, which gives latitude and longitude of a specific place.
But when I have used the same call with wrong place it returns latitude and longitude. How to check whether it is right and wrong?

A typical scenario for using geocoding will be when you know that the address exists and you want to get the location coordinates, maybe to mark on a map. When you search an address in google geocoding api, it will find exact matches and also partial matches to correct for cases like spelling mistakes or multiple spellings in use. Due to partial match, when you search for a word, words close to that in terms of the letters used and the number of letters present will also be found. You can explore 2 options to refine the results:
1, If you want to avoid partial matches , you can try component filtering , where you specify filters on components like locality, country , etc and only exact matches will be returned.
2, You can process the json result in your code by retreiving different components and doing comparisons and taking only cases matching your requirement.
