Difference between view and template in Grails

由 你说的曾经没有我的故事 提交于 2019-12-07 05:11:06
问题 In a Grails app, I am trying to figure out when to use a view and when to use a template for a gsp. Are there any obvious reasons? Or does it just come down to reuse? 回答1: Basically Template is a (reusable) part of a View. Useful for splitting View into logical parts and/or for reusing same code from different views. So, if you're rendering a whole page - use View. If you need just a small part - use Template. See docs for Views and Templates - http://grails.org/doc/latest/guide/theWebLayer

using value of enum in g:select when enum is attribute of selection object

由 假如想象 提交于 2019-12-06 19:10:13
问题 Example: batchTag is an enumerated type attribute of a batchRange, with values like so: JAN1 "January Biweekly 1", JAN2 "January Biweekly 2", etc. I want to display the VALUE of the batchTag in the select, IOW, the select should contain "January Biweekly 1" "January Biweekly 2" ... not JAN1 JAN2 FEB1 FEB2 FEB3 ... I have tried several things in the g:select to do this, but without any success. I thought perhaps "it" would be available as part of the g:select (as it is clearly an iteration)

I'm trying to evaluate a GSP file without a real http request.

Grails iterating in gsp vs. accessing Map elements

由 点点圈 提交于 2019-12-06 10:22:07
问题 Full context: I'm trying to process multiple files using a grails Application. The code I will display comes from the post-processing page where it gives information about the files processed. My initial sense was to use code like this: <table> <tr> <th>Parsed from Excel:</th> <th>Uploaded to DS:</th> <th>File Name:</th> <th>Size:</th> </tr> <tr> <g:each in="${fileContents}" var="item"> <td>${item}</td> </g:each> <%-- <td>${fileContents.ExcelRows?.encodeAsHTML()}</td> <td>${fileContents

Reading the g:datePicker-value in Grails without using the “new Object(params)”-method

由 纵然是瞬间 提交于 2019-12-06 07:36:31
问题 Let's say I have a datePicker called "foobar": <g:datePicker name="foobar" value="${new Date()}" precision="day" /> How do I read the submitted value of this date-picker? One way which works but has some unwanted side-effects is the following: def newObject = new SomeClassName(params) println "value=" + newObject.foobar This way of doing it reads all submitted fields into newObject which is something I want to avoid. I'm only interested in the value of the "foobar" field. The way I originally

I am working on a grails applications and want the ability to do validation on a g:textField. I just want to make sure that numbers are numbers and words are words. I would like to avoid doing it through JS but if that is the only way, then so be it. Here is what I am trying out. <g:textField type="number" pattern="^(?:[-+]?[1-9]\d*|0)?(?:\.\d+)?\$" class="form-control" name="hours" value="${hours}"/></div> Any suggestions or directions?
