ruby - How to update hstore columns in Rails 4 -


Is there a way to restrict hstore columns to be saved? I've got the code to do so by now: 

  store_accessor: widget_locations,: left_area1 ,: mid_area1,: left_area2,: mid_area2,: right_area2

But it still allows to save other key names. update_attributes or update

/ P>

I may be wrong, but my guess is that you widget_locations

< Pre> item.widget_locations [: left_area1] = thing

If so, you can call it 

  item.left_area1 = thing  >

Because you have asked to create the store_accessor attributes : left_area1 ,: mid_area1,: left_area2,: mid_area2,: right_area2 The database will be serialized in the column : widget_locations . Now these attributes will behave like normal attributes, so that you can put the assumptions on them etc.

This lets you update an item as usual: 

  item.update (name: 'test', left_area: 'garden', mid_area: 'livingroom ') Hold

with a hstore will allow be to access the serial column to allow you to add new unknown features, so obvious The best way to reach the specified features is as follows.

c# - Reactive Extensions ControlScheduler -

Well, I'm using Reactive Extension Event Handler to handle my app events, I run the headlines on the Yuri thread. I also use ControlSubular for However, recently I am getting cross thread exception despite using control scheduler and I do not know what the problem is. Code: Observable.FromEventPattern & Lt; String & gt; (CC, "UiAlertMessage", New Control Session ()) Subscribe (_ = & gt; {Alert Control. (Show this language, title, _.EventArgs.UppercaseFirst ());}); The new control scheduler (this) is not to run the code on the UI control thread, so I do not get cross threading exceptions? you should do Observable.FromEventPattern & lt; String & gt; (CC, "UiAlertMessage"). AboveOption (this). Subscribe (_ = & gt; {Alert Control. (Show this language, Titles, _.EventArgs.UppercaseFirst ());}); This is the standard way of sending a scheduler related to specific controls. Passing control scheduler as you have got subsc...

Firefox reacting to JQuery setTimeout that doesn't apply -

& lt; - Only note the first image. I think some jquery is not working in Firefox, where there seems to be a problem ... but there is IE (I know, I know) var hover = $ ('# par1'), box = $ ('.sq1'); Hover.hover (function () {box.toggleClass ('index2');}); and var linkloc = $ ('# par1'), link = $ ('# frnt1'); Linkloc.on ('mouseenter', function () {function linkadd () {link.html ("& lt; a target = _blank href = http: //www.google.co.uk> & lt; img src = small1 .JPG / & gt; & lt; / a & gt; ");} Set Timeout (linkAD, 1500)}); Linkloc.on ('mouseleave', function () {link.html ("& lt; img src = small1.JPG />");}); I appreciate that the code can be a bit messy, but I'm still learning as I go. The problem now is that the top slice of the code is reacting down to the setout. (It revolves around time with setTimeout repeatedly) even though the name of the function is c...
