i have 3 different postgres tables, each containing different types of associates. database fields different each type-- that's why in 3 separate tables. i have 1 component can potentially access type of associate. seems examples i've encountered far, component typically associated 1 graphql query, e.g.: const withdata = graphql(getoneassociate_query, { options({ navid }) { return { variables: { _id: navid} }; } , props({ data: { loading, getoneassociate } }) { return { loading, getoneassociate }; }, }); export default compose( withdata, withapollo )(associateslist); and appears given graphql query, can return single type of record, e.g. in schema: getoneassociate(associatetype: string): [associateaccountingtype] question: possible design graphql schema such single query, can return objects of different types? resolver receive associatetype parameter tell postgres table reference. schema like, r...

i had error being returned after doing build emulator though none shown when doing rebuild. after online research discovered reason might compilesdkversion , buildtoolsversion not matching or compilesdkversion not being supported targetsdkversion. unfortunately changing compilesdkversion 18 doesn't rather returns huge number of errors. have idea how resolve this? compilesdkversion 24 buildtoolsversion "25.0.0" ... minsdkversion 18 targetsdkversion 24 ... compile 'com.android.support:appcompat-v7:24.2.1' if using buildtoolsversion '25.0.0', habe use compilesdkversion 25 if using compilesdkversion 24, have use buildtoolsversion 24.0.3

the problem next: we want know size of vector, can't use size() have function inbounds(vector& arr,int index) returns true if index valid position of vector. so, approach iterate positions. starting @ 1 , duplicating (2,4,8,16,32...) until inbounds returns false, step , repeat search in subrange. let's example, put n = 21: 1 = true 2 = true 4 = true 8 = true 16 = true 32 = false step 16, , search in 16-32 range: (16+1) = true (16+2) = true (16+4) = true (16+8) = false step 20 (16+4) , start over: (20+1) = true (20+2) = false start on in 21: (21+1) = false ok, size 21. this implementation in code: #include <iostream> #include <vector> using namespace std; int inbounds(const vector<int>& arr,int i) { return < arr.size(); } int size(const vector<int>& arr) { int init = 0; while (inbounds(arr,init)) { int start = 2; while (inbounds(arr,init+start)) { ...

i want convert: [:one, :two, :three] to: {one: :one, two: :two, three: three} so far i'm using this: hash[[:basic, :silver, :gold, :platinum].map { |e| [e, e] }] but know if it's possible other way? this use in rails enum definition in model, save values strings in db. i admit hangup: given choice, prefer constructing hashes scratch rather creating array , converting hash.

i need add fragment view dynamically it's inside fragment (see answer https://stackoverflow.com/a/6847770/811405 ). the whole structure this: fragment | |---viewholder | |---(dynamically added fragment) in viewholder, have access view. i've first thought call getcontext() , cast activity, use it's fragment manager add it. however, getcontext returns application object, not activity (it's called on app launch before app physically on screen, maybe activity hasn't been created yet). how can add fragment dynamically on viewholder? (of course, without using terrible anti-patterns) my real problem inflating layout incorrect context (yup, guessed right, application instance) instead of activity. i've fixed code make inflate activity, , getcontext returns activity. fragment manager , add fragment normally.
