Fullcalendar Rails 3.2 - PG::Error
我正在尝试使用rails 3.2为我的应用程序提供fullcalendar，并为dbms使用postgresql。
到了这一点，
在模型event.rb上
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 | class Event < ActiveRecord::Base attr_accessible :all_day, :ends_at, :description, :name, :starts_end scope :BETWEEN, lambda {|start_time, end_time| {:conditions => ["? < starts_at < ?", Event.format_date(start_time), Event.format_date(end_time)] } } # need TO override the json VIEW TO RETURN what full_calendar IS expecting. # http://arshaw.com/fullcalendar/docs/event_data/Event_Object/ def as_json(options = {}) { :id => SELF.id, :name => SELF.name, :description=> SELF.description ||"", :START => starts_at.rfc822, :END => ends_at.rfc822, :allDay => SELF.all_day, :recurring => FALSE, :url => Rails.application.routes.url_helpers.event_path(id), #:color =>"red" } END def SELF.format_date(date_time) TIME.at(date_time.to_i).to_formatted_s(:db) END END |
for starts_at和ends_at我正在使用日期类型(不是日期时间)
在events.js.coffee上
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 | $(document).ready -> $('#calendar').fullCalendar editable: TRUE, header: LEFT: 'prev,next today', center: 'title', RIGHT: 'month,agendaWeek,agendaDay' defaultView: 'month', height: 500, slotMinutes: 30, eventSources: [{ url: '/admin'+'/events', }], timeFormat: 'h:mm t{ - h:mm t} ', dragOpacity:"0.5" eventDrop: (event, dayDelta, minuteDelta, allDay, revertFunc) -> updateEvent(event); eventResize: (event, dayDelta, minuteDelta, revertFunc) -> updateEvent(event); updateEvent = (the_event) -> $.update"/events/" + the_event.id, event: name: the_event.name, starts_at:"" + the_event.start, ends_at:"" + the_event.end, description: the_event.description |
在控制器admin / events_controller.rb上
1 2 3 4 5 6 7 8 9 | def INDEX @events = Event.scoped @events = Event.between(params['start'], params['end']) IF (params['start'] && params['end']) respond_to do |format| format.html # INDEX.html.erb format.json { render json: @events } END END |
首先，我插入一个事件并成功，当运行到localhost：3000 / admin / events /我得到以下错误，如
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | Event LOAD (14.0ms) SELECT"events".* FROM"events" WHERE ('2012-11-25 00:00: 00' < starts_at < '2013-01-06 00:00:00') PG::Error: ERROR: syntax error at OR near"<" LINE 1: ...events" WHERE ('2012-11-25 00:00:00' < starts_at < '2013-01... ^ : SELECT"events".* FROM"events" WHERE ('2012-11-25 00:00:00' < starts_at < '2 013-01-06 00:00:00') Completed 500 Internal Server Error in 100ms ActiveRecord::StatementInvalid (PG::Error: ERROR: syntax error at or near"<" LINE 1: ...events" WHERE ('2012-11-25 00:00:00' < starts_at < '2013-01... ^ : SELECT"events".* FROM"events" WHERE ('2012-11-25 00:00:00' < starts_at < '2 013-01-06 00:00:00')): |
更新
改变条件
1 2 3 4 | {:conditions => [ "starts_at > ? and starts_at < ?", Event.format_date(start_time), Event.format_date(end_time) ] } |
并且在命令的帮助下
1 2 3 | Event LOAD (2.0ms) SELECT"events".* FROM"events" WHERE (starts_at > '2012-1 -25 00:00:00' AND starts_at < '2013-01-06 00:00:00') ompleted 200 OK IN 31ms (Views: 15.0ms | ActiveRecord: 12.0ms) |
但事件没有显示在日历中:(
更新2
我正在尝试示例应用程序
和事件显示。

注意：资源事件
这是我的应用程序
1 2 3 4 5 6 7 8 9 10 11 | Started GET"/admin/events?start=1353776400&end=1357405200&_=135556713595 4" FOR 127.0.0.1 at 2012-12-15 17:25:36 +0700 Processing BY Admin::EventsController#index AS JSON Parameters: {"start"=>"1353776400","end"=>"1357405200","_"=>"1355567135954"} Admin LOAD (2.0ms) SELECT"public"."admins".* FROM"public"."ad mins" WHERE"public"."admins"."id" = 25 LIMIT 1 Account LOAD (6.0ms) SELECT"public"."accounts".* FROM"public"."accounts" WH ERE"public"."accounts"."admin_id" = 25 LIMIT 1 Event LOAD (3.0ms) SELECT"events".* FROM"events" WHERE (starts_at > '2012-1 1-25 00:00:00' AND starts_at < '2013-01-06 00:00:00') Completed 200 OK IN 101ms (Views: 72.0ms | ActiveRecord: 24.0ms) |
注意：命名空间管理员(admin / event)下的资源事件，我有多租户模式，管理员使用公共模式登录后登录更改为其他模式(子域)。
我将类型日期更改为日期时间
在psql上
1 2 3 4 5 6 7 8 9 10 | education_development=# SELECT * FROM subdomain.events WHERE (starts_at > '2 012-11-25 00:00:00' AND starts_at < '2013-01-06 00:00:00') education_development-# ; id | name | starts_at | ends_at | all_day | description | created_at | updated_at ----+---------------+------------------------+------------------------+--------- +-----------------+----------------------------+---------------------------- 1 | NEW YEAR 2013 | 2013-01-01 00:00:00+07 | 2013-01-01 00:00:00+07 | f | NEW YEAR 2013 | 2012-12-15 06:53:50.695456 | 2012-12-15 06:53:50.695456 (1 ROW) |
谁能帮我？
谢谢 ：)
你不能不喜欢：
1 | a < starts_at < b |
在WHERE子句中，这只是无效的SQL。 但是，您可以：
1 | starts_at > a AND starts_at < b |
你可能想要：
1 2 3 4 | {:conditions => [ "starts_at > ? and starts_at < ?", Event.format_date(start_time), Event.format_date(end_time) ] } |
顺便说一句，带参数的作用域的推荐方法是使用类方法：
Using a class method is the preferred way to accept arguments for scopes.
所以你可能想要：
1 2 3 4 5 6 | def SELF.between(start_time, end_time) WHERE('starts_at > :lo and starts_at < :up', :lo => Event.format_date(start_time), :up => Event.format_date(end_time) ) END |
