eclipse - Type error when mocking Slick Query using ScalaMock: what does "some other" mean? -


i have used java several years, i'm new scala , still trying figure out type system. i'm using scala 2.10.2, slick 1.0.1, , scalamock 2.10-3.0-m4 in eclipse scala ide 3.0.1

i'm trying mock out slick in updatenamebyid using scalamock.

def updatenamebyid(id: int, input: string, users: richtable[object]) = {     users.where(_.id === id).map{ e => e.test }.update(input) }  abstract class richtable[t](name: string = "blank")          extends slick.driver.mysqldriver.simple.table[t](name) {     def id = column[int]("id", o.primarykey, o.autoinc)     def test = column[string]("test") }

(i'm passing in users: richtable[user] user has complex inheritance hierarchy, i've temporarily removed uses of user simplify example)

users.where returns scala.slick.lifted.query, try mock out follows

class modeltest extends flatspec mockfactory {     def test = {         val mockusers = mock[richtable[object]]         // mockquery definition         val mockquery = mock[scala.slick.lifted.query[richtable[object],             scala.slick.lifted.nothingcontainer#tablenothing]]         (mockusers.where _).expects(*).returns(mockquery)         main.updatenamebyid(1, "asdf", mockusers)     } }

the mockquery definition gives me these cryptic type errors

type mismatch; found : scala.slick.lifted.query[o(in method union),     scala.slick.lifted.nothingcontainer#tablenothing] required: scala.slick.lifted.query[(some other)o(in method union),     scala.slick.lifted.nothingcontainer#tablenothing]  type mismatch; found : scala.slick.lifted.query[o(in method unionall),     scala.slick.lifted.nothingcontainer#tablenothing] required: scala.slick.lifted.query[(some other)o(in method unionall),     scala.slick.lifted.nothingcontainer#tablenothing]

i have no idea "o(in method union[all])" vs. "(some other)o(in method union[all])" means, , google hasn't been (it doesn't matters "some other" extremely generic phrase - googling "scala other type error" produces pretty same results "scala type error"). know means and/or how fix type error?

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!

ios - Show keyboard with UITextField in the input accessory view -

i have buttona , when buttona clicked, want keyboard show uitextfield in inputaccessoryview. there way have keyboard show manually , set inputaccessoryview without having uitextfield initially? thanks. you cannot summon keyboard without object can become first responder. there 2 ways work around: subclass uiview , implement uikeyinput protocol in it. example: in .h file: @interface inputobject : uiview<uikeyinput> @property (nonatomic, copy) nsstring *text; @property (nonatomic, strong) uiview *inputaccessoryview; // must override inputaccessoryview , since it's readonly default @end in .m file, implement protocol: - (bool)canbecomefirstresponder { return yes; } - (bool)hastext { return [self.text length]; } - (void)inserttext:(nsstring *)text { nsstring *selftext = self.text ? self.text : @""; self.text = [selftext stringbyappendingstring:text]; [[nsnotificationcenter defaultcenter] postnotificationname:kinputobjec...
