ruby on rails - Associated model is not saving data when page is refreshed -

-

rails 3.1 rc4

i have 1:1 association between user , profile. when submit new profile form, data i've entered displayed fine (see screenshot: http://i.imgur.com/fy8yu.png), when refresh data instantly wiped.

could tell me causing this?

here's submit form:
<%= form_for([@user, @user.build_profile]) |f| %>
<div class="field">
<%= f.label :first_name %><br />
<%= f.text_field :first_name %>
</div>
<div class="field">
<%= f.label :last_name %><br />
<%= f.text_field :last_name %>
</div>
<div class="field">
<%= f.label :picture %><br />
<%= f.text_field :picture %>
</div>
<div class="field">
<%= f.radio_button(:sex, "male") %>
<%= f.label(:sex, "male") %>
<%= f.radio_button(:sex, "female") %>
<%= f.label(:sex, "female") %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>

here's users_controller: https://github.com/imjp/supermodel/blob/master/app/controllers/users_controller.rb

here's profiles_controller: https://github.com/imjp/supermodel/blob/master/app/controllers/profiles_controller.rb

i'm not sure agree approach. why don't this:

in models/user.rb:

accepts_nested_attributes_for :profile

in controllers/users_controller.rb:

def new   @user = user.new   @user.build_profile end

in views/users/_form.html.erb:

<%= form_for @user |f| %>   <%= f.text_field :first_name %>   <%= f.fields_for :profile |pf| %>     <%= pf.text_field :some_profile_field %>   <% end -%> <%- end -%>

this isn't copied or tested, should work. on saving user, profile fields sent along , validated user fields , re-rendered when rendering form again after save error. way keep full control on form , contents minimal effort.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
