<p>Scenario</p>
<p>I am using database/sql to query a database using db.Query and am placing the data from the table into a slice of structs. At this point i am displaying the information in my template by ranging over the slice and displaying the info. This is actually working the way I intended it to.</p>
<p>One of the fields is displays date information and I would like to include a date select field on the template to allow the user to only show dates after a date.</p>
<p>How should I go about handling this? </p>
<p>The options that I have considered so far
1) write front end code to handle filtering on the client machine
2) POST date from date field and use POST data to re-query the database and display new information.</p>
<p>I am new to go so any ideas, guidance or criticism is welcome.</p>
