For my rails photo gallery site I needed the ability to bulk add descriptions and tags to my images.
Finding, loading, editing, saving each photo individually is painful.
I recently discovered a little quirk involving VPS servers and Ruby Gems.
I’ve started learning Ruby on Rails and the Ruby part uses things called ‘Gems’ in a similar way to Perl using Modules. I wanted to install a new gem on my server to support some Paypal integration, but ‘gem’ kept segfaulting on me. To break the cycle, you simply use: So the problem still wasn’t resolved!
The search API is used to query one or more indices either using simple [query string queries]( as the `:q` argument , or by passing the [full request definition]( in the [Query DSL]( as the `:body` argument.
127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 Update a document without sending the whole document in the request (“partial update”).
You can leave out the `:id` parameter for the ID to be generated automatically Delete documents which match specified query.
Provide the query either as a “query string” query in the `:q` argument, or using the Elasticsearch's [Query DSL]( in the `:body` argument. Percolator allows you to register queries and then evaluate a document against them: the IDs of matching queries are returned in the response.
The way to avoid this problem is to update Ruby Gems… Unfortunately, this was not in my local repository.I decided to create a form to edit a page of images at one time. edited file: config/Add the view for the bulk_update action. The each loop shown below outputs the tabular image data, and the fields_for method uses a partial to render the form fields.file: app/views/images/bulk_Added the bulk_update_save method to the images controller.See full example for Elasticsearch 5.x and higher in Efficiently iterate over a large result set.When using `from` and `size` to return a large result sets, performance drops as you “paginate” in the set, and you can't guarantee the consistency when the index is being updated at the same time.Here’s what the Bundler doc says about bundle update UPDATING A LIST OF GEMS Sometimes, you want to update a single gem in the Gemfile(5), and leave the rest of the gems that you specified locked to the versions in the So when your app breaks or your tests fail, it takes a lot of time to figure out why.For instance, in the scenario above, imagine that nokogiri releases version 1.4.4, and you want to update it without updating Rails and all of its dependencies. Bundler will update nokogiri and any of its dependencies, but leave alone Rails and its dependencies. Want an example of an unexpected side-effect of bundle update? Let’s say you’ve installed the sextant gem into your Rails app so you can see your Rails routes in development mode by navigating to /rails/routes.[Update: added example of updating the sextant gem, which causes Rails to be updated as well.] [Another update: see the comment below from Andy Waite about an official, approved, documented way to update as few gems as possible.] Hey Ruby developers, When you run bundle update to update your gems, it updates all of them at once.If your app stops working or your tests start failing, it can be pretty hard to figure out which gem update broke it.(It saves time compared to rake routes since the environment is already loaded.) In this example you are on Rails 3.2.2 and sextant 0.1.2. I don’t know about you, but I don’t like having my version of Rails updated just because I got the latest version of some little helpful gem.Now you run bundle update sextant to update to 0.1.3. When writing this blog post I tried a few scenarios.
