    <p>Newbie question....</p> <p>Trying to start a project in rails. I have different spreadsheets in csv format I'd like to import into the MySQL database to be able to manipulate the data.</p> <p>After looking around on stackoverflow, Google, etc. I wrote a rake task requiring fastercsv to do the job. I keep getting errors so hopefully you can help.</p> <p>... <strong>Ok so I changed the code to use 'csv' vs 'fastercsv'...still getting errors</strong>. See below</p> <p>New Code for Rake File (take 3):</p> <pre><code>require 'csv' desc "Import gac from csv file" task :import =&gt; [:environment] do file = "gac.csv" CSV.foreach(file, :headers =&gt; true) do |row| Institution.create({ :institution_name =&gt; row[0], :website =&gt; row[1], :email =&gt; row[2], :category_1 =&gt; row[3], :category_2 =&gt; row[4], :category_3 =&gt; row[5], :category_4 =&gt; row[6], :category_5 =&gt; row[7], :category_6 =&gt; row[8], :category_7 =&gt; row[9], :category_8 =&gt; row[10], :category_9 =&gt; row[11], :category_10 =&gt; row[12], :category_11 =&gt; row[13], :institution_description =&gt; row[14] }) end end </code></pre> <p><strong>Error Codes:</strong></p> <pre><code>Daves-MacBook-Pro:vendor dave$ rake import --trace ** Invoke import (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute import rake aborted! invalid byte sequence in UTF-8 /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1855:in `sub!' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1855:in `block in shift' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1849:in `loop' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1849:in `shift' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1791:in `each' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1208:in `block in foreach' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1354:in `open' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/csv.rb:1207:in `foreach' /Users/dave/rails_projects/vendor/lib/tasks/import.rake:8:in `block in &lt;top (required)&gt;' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/task.rb:205:in `call' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/task.rb:205:in `block in execute' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/task.rb:200:in `each' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/task.rb:200:in `execute' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/task.rb:158:in `block in invoke_with_call_chain' /Users/dave/.rvm/rubies/ruby-1.9.3-p0/lib/ruby/1.9.1/monitor.rb:211:in `mon_synchronize' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/task.rb:151:in `invoke_with_call_chain' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/task.rb:144:in `invoke' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:116:in `invoke_task' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:94:in `block (2 levels) in top_level' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:94:in `each' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:94:in `block in top_level' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:88:in `top_level' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:66:in `block in run' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:133:in `standard_exception_handling' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/application.rb:63:in `run' /Users/dave/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/bin/rake:33:in `&lt;top (required)&gt;' /Users/dave/.rvm/gems/ruby-1.9.3-p0/bin/rake:19:in `load' /Users/dave/.rvm/gems/ruby-1.9.3-p0/bin/rake:19:in `&lt;main&gt;' Tasks: TOP =&gt; import </code></pre>

    2. COAnd could you please tell me, why are you using `FasterCSV` **gem** instead of `CSV` **inbuilt class** of ruby?? Try: `require 'csv'` instead?

    3. CO@Surya: Right, 1.9's standard csv is pretty much FasterCSV with improved UTF-8 support, there's no need for FasterCSV unless you're stuck with 1.8.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
