139 00:07:55,040 --> 00:07:57,970 ‫But actually, we're not gonna be able to replace 140 00:07:57,970 --> 00:08:01,710 ‫all of the functions that we have here with factories, 141 00:08:01,710 --> 00:08:03,670 ‫because otherwise, we wouldn't even need 142 00:08:03,670 --> 00:08:05,480 ‫this controller file, right? 143 00:08:05,480 --> 00:08:08,750 ‫We could then simply create these handlers on the fly, 144 00:08:08,750 --> 00:08:11,270 ‫basically, in the router file, right? 145 00:08:11,270 --> 00:08:13,947 ‫And so, we could basically skip this entire step 146 00:08:13,947 --> 00:08:16,320 ‫of the controller file. 147 00:08:16,320 --> 00:08:17,600 ‫But again, we still need it 148 00:08:17,600 --> 00:08:19,730 ‫because we have some other stuff in there. 149 00:08:19,730 --> 00:08:23,080 ‫For example, these methods here 150 00:08:23,080 --> 00:08:27,418 ‫for getting the tour statistics, or this monthly plan, 151 00:08:27,418 --> 00:08:29,560 ‫and yeah. 152 00:08:29,560 --> 00:08:33,750 ‫So it makes sense to actually keep this file, okay?

160 00:08:49,150 --> 00:08:54,140 ‫But we can do it in the review controller, okay? 161 00:08:54,140 --> 00:08:58,230 ‫So basically, we want to replace this createReview. 162 00:08:58,230 --> 00:08:59,990 ‫Now you see that also, in this one, 163 00:08:59,990 --> 00:09:01,840 ‫we have some additional step. 164 00:09:01,840 --> 00:09:04,170 ‫So we have this code that is also not 165 00:09:04,170 --> 00:09:07,330 ‫in our generic createOne function. 166 00:09:07,330 --> 00:09:09,165 ‫And so, how can we fix that? 167 00:09:09,165 --> 00:09:11,800 ‫Well, we can actually create a middleware 168 00:09:11,800 --> 00:09:15,610 ‫that is going to run before the createReview, okay? 169 00:09:15,610 --> 00:09:19,170 ‫And so, that actually also makes it a bit more decoupled. 170 00:09:19,170 --> 00:09:22,610 ‫So basically, this code here is then gonna be 171 00:09:22,610 --> 00:09:23,960 ‫in its own function, 172 00:09:23,960 --> 00:09:26,430 ‫and really decoupled from createReview, 173 00:09:26,430 --> 00:09:28,550 ‫because actually, it doesn't have much to do 174 00:09:28,550 --> 00:09:30,400 ‫with creating the review. 175 00:09:30,400 --> 00:09:32,630 ‫It simply sets some data, right? 176 00:09:32,630 --> 00:09:37,627 ‫And so, let's actually call this set tour and user IDs. 177 00:09:41,720 --> 00:09:44,173 ‫So request, ah, the response is missing. 178 00:09:47,200 --> 00:09:48,504 ‫Okay? 179 00:09:48,504 --> 00:09:50,110 ‫And all we're gonna do here 180 00:09:50,110 --> 00:09:53,730 ‫is to basically set these IDs on the body 181 00:09:53,730 --> 00:09:56,100 ‫and then move straight to the next middleware, 182 00:09:56,100 --> 00:09:58,660 ‫where then the review is actually created. 183 00:09:58,660 --> 00:09:59,650 ‫Alright? 184 00:09:59,650 --> 00:10:01,350 ‫So before we forget it, 185 00:10:01,350 --> 00:10:04,430 ‫let's then actually add this middleware. 186 00:10:04,430 --> 00:10:08,993 ‫So in the review routes, it's right here in post. 187 00:10:10,780 --> 00:10:13,467 ‫So reviewController, setTourUserIds. 188 00:10:15,700 --> 00:10:16,533 ‫Okay?
