It looks like there is a typo in the getPage function. I’ve fixed it in the post. Rather than this:


<cfset variables.page = arguments.page>
<cfset var personData = ...>


it should have read:


<cfset var personData = 0>
<cfset variables.page = arguments.page>
<cfset personData = ...>


select top #pageSize# *
from mstproperty
where
1=1
#where#
and pid not in (
select top #recordsToSkip# pid
from mstproperty
where
1=1
#where#
#orderBy#
)
#orderBy#

select count(*) as num
from mstproperty
where
1=1
#where#

and second file contains below details,

and i a am using the below file for calling the coldfusion component file to my application for arrive the pagination in my application,file name called pagination1.cfm

and marketid = 3 and propertytypeid = 2 and statusid not in (1,7)

order by propertyname

#lastName#, #firstName#

Previous
Page #page# of #totalPages#
Next

but when i ran the above code i got the below error

kindly help us to resolve this.

Thanks in advance.

1. The gateway would be used something like this:

<!— First create the gateway object separately —>
<cfset personGateway = createObject("component","PersonGateway").init(dsn)>

<!— Then create the pagination and provide the gateway as a parameter —>
<cfset paginator = createObject("component","PersonPaginator").init(
personGateway,
30,
"and isActive=1",
"order by lastName asc, firstName asc"
)>

This type of relationship is called composition (the gateway is "composed" inside the paginator). Composition is a generally preferred relationship over inheritance (where the paginator extends the gateway).

Inside the paginator, whenever you need to use the gateway you would refer to variables.personGateway

2. It should be named PersonPaginator. Thanks, I have fixed this.

3. Thanks, fixed.

4. I can see what you are getting at. What was missing was the page should have been set inside the getPage() function and the page should have been initialised to zero. Not sure about setting the current page on init() and then /also/ passing it in to the getPage() function. I think I will leave it out of the init() for now.

5. Thanks, fixed.

6. Yes, would be nicer to include the cfoutput’s

Thanks for letting me know about this swarm of typos!

1. I really don’t understand how do you use/call the "gateway", what I did is to extend from the "gateway" in the peoplePaginator component

?????? no idea how to use this: <cfset variables.peopleGateway = arguments.peopleGateway>

My solution: <cfcomponent extends="peoplegateway" output="false">

2. You named the component "PeoplePaginator" but you are calling it as a "PersonPaginator". That is ambigous and it doesn’t work (at least for me)

3. In getNumberOfPages function, when you are doing the "mod" calc, you are using the wrong var

WRONG: <cfif totalPages mod variables.pageSize gt 0>
GOOD: <cfif totalRecords mod variables.pageSize gt 0>

4. On PeoplePaginator init, I think you need to pass the current page number as an argument

+++ when using the object +++
<cfparam name="url.page" default="1">
<cfset page = url.page>

<cfset paginator.init(
10,
"and isActive=1",
"order by lastName asc, firstName asc",
page <<<—- This is the new parameter
)>
+++++

=== init function within the component ===
<cffunction name="init" output="false">
<cfargument name="pageSize">
<cfargument name="where">
<cfargument name="orderBy">
<cfargument name="currentPageNumber"> <<<—- This is the new argument
<cfset variables.pageSize = arguments.pageSize>
<cfset variables.where = arguments.where>
<cfset variables.orderBy = arguments.orderBy>
<cfset variables.page = arguments.currentPageNumber> <<<—- This is the new argument
</cffunction>
======

5. This function is not returning a value getNextPageNumber

6. Here you have to put the output coldfusion tags:
<cfoutput><a href="test.cfm?page=#prevPage#">Previous</a>
Page #page# of #totalPages#
<a href="test.cfm?page=#nextPage#">Next</a></cfoutput>

I think there are others errors but I dind’t track them. If you want to download the code (working) you can do it from: http://dev.dualcredit.itap.purdue.edu/mescalito2-paginator.rar
and by the way, remember to change the datasources

Looks like this may be simpler in MySQL than in MSSQL2000; we don’t need the subquery. Looking up the LIMIT syntax – http://dev.mysql.com/doc/refman/5.0/en/select.html – looks like we get something like:

<cfset pageSize = 30>
<cfset page = page + 1>
<cfset recordsToSkip = (page – 1) * pageSize>

<cfquery name="getLabour" datasource="andes">
select *
from control_lab
where proID = ‘#URL.proID#’
and empID = ‘#getNames.empID#’
order by proDate desc
limit #recordsToSkip#, #pageSize#
</cfquery>

I haven’t tested this but, who knows, it might just work.
