when I used excel-export:0.2.1 plug-in use in Grails but problem is that its append (') star with number
like '08:00:00 Pm shows in excel formula bar,how to fixed this problem
Convert the property to a String. You can use a formatter closure supported by the plugin.
def title = { domain, value ->
return value.toString()
}

in a app, I use jQueryTablesorter, and the widget https://mottie.github.io/tablesorter/docs/example-widget-filter.html
I have two main features :
- filtering (the widget)
- sorting (default feature)
Both of these feature use textExtraction() function,
https://mottie.github.io/tablesorter/docs/#textextraction
My problem is the following :
for sorting, I would like to use computer form of a date, that is "2020-04-01"
for filtering, I would like to use human form (in French "1er avril 2020").
How can I deal with it ?
You might need to use a date library like sugar or date.js - check out this demo: https://mottie.github.io/tablesorter/docs/example-parsers-dates.html. What that library does is use the parser to convert the filter into a normalized date that will match with the date in the column. You would also need to add a filter-parsed class name to the column (ref).
I have found. I need to use a hook which modify the value parsed for filtering.
$.tablesorter.filter.types.start = function(config, data) {
data.exact = data.$cells[data.index];
data.exact = data.exact.innerText;
data.iExact = data.exact.toLowerCase();
return null;
}
Why is it that my query does not work ?
Form1.ABSQuery1.Close;
Form1.ABSQuery1.SQL.Clear;
Form1.ABSQuery1.SQL.Text:='DELETE FROM LOG WHERE status = ''YES'' and DATE BETWEEN :d1 and :d2';
Form1.ABSQuery1.Params.ParamByName('d1').Value :=cxDateEdit1.Date;
Form1.ABSQuery1.Params.ParamByName('d2').Value :=cxDateEdit2.Date;
Form1.ABSQuery1.ExecSQL;
Form1.ABSTable1.Refresh;
I get this error :
You should be using AsDateTime in your Params setting code.
Form1.ABSQuery1.SQL.Text:='DELETE FROM LOG WHERE status = ''YES'' and DATE BETWEEN :d1 and :d2';
Form1.ABSQuery1.Params.ParamByName('d1').AsDateTime :=cxDateEdit1.Date;
Form1.ABSQuery1.Params.ParamByName('d2').AsDateTime :=cxDateEdit2.Date;
Form1.ABSQuery1.ExecSQL;
Using Value converts the cxDateEdit1.Date to a generic string format for assignment, and that doesn't properly convert it to the YYYY-MM-DD format that most databases (including ABS) expect. Properly using AsDateTime allows the database driver/component to convert to the specific date format the DBMS uses.
Also, is your database field really named DATE? Date is usually a reserved word or function name in most DBMS, and if it is it usually needs to be quoted.
Form1.ABSQuery1.Params.ParamByName('d1').DataType := ftDateTime;
Form1.ABSQuery1.Params.ParamByName('d1').Value :=cxDateEdit1.Date;
You must explicitly specify the data type of the parameter to it had no such problem, and then convert to a string does not need to
I'm using Grails 1.3.4 with the export 0.9.5 plug in.
I have a formatter that I use that sets the date format to 'YYYY-MM-DD' when exporting to excel. But this doesn't change the data type. The date is exported to Excel as a string/general data type.
def dateFormat = { domain, value ->
if(value instanceof Date){
return new java.text.SimpleDateFormat("yyyy-MM-dd").format(value)
}
return value
}
Map formatters = [ecd:dateFormat, completed:dateFormat, dateCreated:dateFormat, approvedDate:dateFormat, dpaECD:dateFormat]
exportService.export(params.format, response.outputStream,exportList, jobService.parseColNames(columns), labels, formatters, null)
Is there a way to export data and set the datatype of a column in excel so the user doesn't have to manually set the cell/column formatting to 'Date' every time after exporting?
Are you sure you want to use that plugin? It didn't work so well to me.
I've been using the JXL plugin for Grails for a while and it works perfectly.
It even has an option to write the Excel file to the response, so that the user can directly download the file using my REST service.
The link is: http://grails.org/plugin/jxl
Here is an example of how simple it is to create workbooks:
new ExcelBuilder().workbook('/path/to/test.xls') {
sheet('SheetName') {
cell(0,0,'Current Date')
cell(0,1,new Date())
}
}
Note that the cell() method has 3 parameters: column, row and value. This third parameter can be a number, string or date, and it formats it perfectly.
You can find more information here.
We recently purchased a highcharts license and have integrated it with our Grails application.
We're having some difficulty in that we're unable to specify a tool tip formatter in the JSON object that we're returning because it appears that the HighCharts JSON object doesn't conform to the JSON standards.
Specifically, it appears that JSON is not technically allowed to have JavaScript functions as an object property. From the www.json.org website:
A string is a sequence of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a single character string. A string is very much like a C or Java string.
So, when we output our formatting string, it gets wrapped in double quotes, like this:
"formatter": "this.x + ': ' + this.y",
Can we get an enhancement where we specify a tooltip (or tooltip-fn) property as a string, which is the name of a javascript function? For example:
"formatter": "myTooltipFn"
which calls a javascript function like:
myTooltipFn(chart) {
return chart.x
}
I've just fixed this after hours of labour. My solution was to add the formatter to the data AFTER the data is sent in JSON format to the browser.
So basically, in the js file that has this line:
$(blah).highcharts(data);
write BEFORE this line:
Data.tooltip.formatter = function() {
//write function here
}
I have created a domain with a Double field. When the validation occurs it throws the error message with size value showing the number with commas. Following are the detials
Groovy Class
class Quote {
String content;
Double size;
static constraints = {
content(maxSize:1000, blank:false)
size(min: 0.00D, max:999.99D)
}
}
Value entered "11111", error obtained "Size 11,111 is exceeded the limit". I have added the property key/value pair in messages.properties.
Here, I would like to get the message back without the commas. My main aim is to take the key and format the message returned based on my requirements. I require this as I have other fields that need conversion. For example, a date is validated but when showing the error the Gregorian date needs to be converted to an Islamic date and shown to user.
Does anyone know if I can do something to make this work.
I have tried the solution provided in http://ishanf.tumblr.com/post/434379583/custom-property-editor-for-grails but this did not work.
I have also tried modifying the messages values, but this is not flexible in case of my date issue. Example, for a key value pair, instead of using {2} as a place holder I could use {2, date, mm/dd/yyyy}, but for Islamic dates I want to format and show things differently.
Also, please note I have created a separate key for default date formatting for my application.
Would appreciate the help.
In grails, the return of a constrain is an already translated string.
You can create a taglib to format that, or enhance the
Another option would be custom validators. A custom validator can return false or a key when failing.
For example in your domain class, to vaildate a field:
myDateField validator: {val, obj -> obj.myShinyDateValidatorMethod(val) }
private myShinyDateValidatorMethod() {
if (isNotValidDate(val) {
return [the_message_key, val.formatedAsYouWand]
}
}
and, in your properties file you have to have defined the key:
the_message_key=This date: {3} is not valid
The trick here is that in the return from the validator, first string is the key and the rest are parameters for that key, but grails already uses {0}, {1}, {2} placeholders for className, fieldName and value, and the first parameter that you pass will be used as {3} placeholder.
Hope this helps
